Parotid Gland: The largest of the three pairs of SALIVARY GLANDS. They lie on the sides of the FACE immediately below and in front of the EAR.Parotid Neoplasms: Tumors or cancer of the PAROTID GLAND.Parotid DiseasesSalivary Glands: Glands that secrete SALIVA in the MOUTH. There are three pairs of salivary glands (PAROTID GLAND; SUBLINGUAL GLAND; SUBMANDIBULAR GLAND).Adenolymphoma: A benign tumor characterized histologically by tall columnar epithelium within a lymphoid tissue stroma. It is usually found in the salivary glands, especially the parotid.Submandibular Gland: One of two salivary glands in the neck, located in the space bound by the two bellies of the digastric muscle and the angle of the mandible. It discharges through the submandibular duct. The secretory units are predominantly serous although a few mucous alveoli, some with serous demilunes, occur. (Stedman, 25th ed)Amylases: A group of amylolytic enzymes that cleave starch, glycogen, and related alpha-1,4-glucans. (Stedman, 25th ed) EC 3.2.1.-.Sublingual Gland: A salivary gland on each side of the mouth below the TONGUE.Salivary Proteins and Peptides: Proteins and peptides found in SALIVA and the SALIVARY GLANDS. Some salivary proteins such as ALPHA-AMYLASES are enzymes, but their composition varies in different individuals.Adenoma, Pleomorphic: A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth. (Dorland, 27th ed)Salivary Ducts: Any of the ducts which transport saliva. Salivary ducts include the parotid duct, the major and minor sublingual ducts, and the submandibular duct.Salivation: The discharge of saliva from the SALIVARY GLANDS that keeps the mouth tissues moist and aids in digestion.Parotitis: INFLAMMATION of the PAROTID GLAND.Exocrine Glands: Glands of external secretion that release its secretions to the body's cavities, organs, or surface, through a duct.Salivary Gland DiseasesXerostomia: Decreased salivary flow.Sialography: Radiography of the SALIVARY GLANDS or ducts following injection of contrast medium.Salivary Gland Neoplasms: Tumors or cancer of the SALIVARY GLANDS.Saliva: The clear, viscous fluid secreted by the SALIVARY GLANDS and mucous glands of the mouth. It contains MUCINS, water, organic salts, and ptylin.Mammary Glands, Animal: MAMMARY GLANDS in the non-human MAMMALS.Proline-Rich Protein Domains: Protein domains that are enriched in PROLINE. The cyclical nature of proline causes the peptide bonds it forms to have a limited degree of conformational mobility. Therefore the presence of multiple prolines in close proximity to each other can convey a distinct conformational arrangement to a peptide chain.Aquaporin 5: Aquaporin 5 is a water-specific channel protein that is expressed primarily in alveolar, tracheal, and upper bronchial EPITHELIUM. It plays an important role in maintaining water HOMEOSTASIS in the LUNGS and may also regulate release of SALIVA and TEARS in the SALIVARY GLANDS and the LACRIMAL GLAND.Isoproterenol: Isopropyl analog of EPINEPHRINE; beta-sympathomimetic that acts on the heart, bronchi, skeletal muscle, alimentary tract, etc. It is used mainly as bronchodilator and heart stimulant.Carcinoma, Mucoepidermoid: A tumor of both low- and high-grade malignancy. The low-grade grow slowly, appear in any age group, and are readily cured by excision. The high-grade behave aggressively, widely infiltrate the salivary gland and produce lymph node and distant metastases. Mucoepidermoid carcinomas account for about 21% of the malignant tumors of the parotid gland and 10% of the sublingual gland. They are the most common malignant tumor of the parotid. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p575; Holland et al., Cancer Medicine, 3d ed, p1240)Carcinoma, Acinar Cell: A malignant tumor arising from secreting cells of a racemose gland, particularly the salivary glands. Racemose (Latin racemosus, full of clusters) refers, as does acinar (Latin acinus, grape), to small saclike dilatations in various glands. Acinar cell carcinomas are usually well differentiated and account for about 13% of the cancers arising in the parotid gland. Lymph node metastasis occurs in about 16% of cases. Local recurrences and distant metastases many years after treatment are common. This tumor appears in all age groups and is most common in women. (Stedman, 25th ed; Holland et al., Cancer Medicine, 3d ed, p1240; from DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p575)Salivary Glands, Minor: Accessory salivary glands located in the lip, cheek, tongue, floor of mouth, palate and intramaxillary.Salivary Gland Fistula: A fistula between a salivary duct or gland and the cutaneous surface of the oral cavity.Sjogren's Syndrome: Chronic inflammatory and autoimmune disease in which the salivary and lacrimal glands undergo progressive destruction by lymphocytes and plasma cells resulting in decreased production of saliva and tears. The primary form, often called sicca syndrome, involves both KERATOCONJUNCTIVITIS SICCA and XEROSTOMIA. The secondary form includes, in addition, the presence of a connective tissue disease, usually rheumatoid arthritis.Myoepithelioma: A usually benign tumor made up predominantly of myoepithelial cells.Salivary Duct Calculi: Presence of small calculi in the terminal salivary ducts (salivary sand), or stones (larger calculi) found in the larger ducts.Sweat Glands: Sweat-producing structures that are embedded in the DERMIS. Each gland consists of a single tube, a coiled body, and a superficial duct.Carbachol: A slowly hydrolyzed CHOLINERGIC AGONIST that acts at both MUSCARINIC RECEPTORS and NICOTINIC RECEPTORS.Pilocarpine: A slowly hydrolyzed muscarinic agonist with no nicotinic effects. Pilocarpine is used as a miotic and in the treatment of glaucoma.Submandibular Gland NeoplasmsSweating, Gustatory: An autonomic disorder characterized by excessive sweating of the forehead, upper lip, perioral region, or sternum subsequent to gustatory stimuli. The auriculotemporal syndrome features facial flushing or sweating limited to the distribution of the auriculotemporal nerve and may develop after trauma to the parotid gland, in association with PAROTID NEOPLASMS, or following their surgical removal. (From Ann Neurol 1997 Dec;42(6):973-5)Lacrimal Apparatus: The tear-forming and tear-conducting system which includes the lacrimal glands, eyelid margins, conjunctival sac, and the tear drainage system.Sebaceous Glands: Small, sacculated organs found within the DERMIS. Each gland has a single duct that emerges from a cluster of oval alveoli. Each alveolus consists of a transparent BASEMENT MEMBRANE enclosing epithelial cells. The ducts from most sebaceous glands open into a HAIR FOLLICLE, but some open on the general surface of the SKIN. Sebaceous glands secrete SEBUM.Harderian Gland: A sebaceous gland that, in some animals, acts as an accessory to the lacrimal gland. The harderian gland excretes fluid that facilitates movement of the third eyelid.Submandibular Gland DiseasesParasympathetic Nervous System: The craniosacral division of the autonomic nervous system. The cell bodies of the parasympathetic preganglionic fibers are in brain stem nuclei and in the sacral spinal cord. They synapse in cranial autonomic ganglia or in terminal ganglia near target organs. The parasympathetic nervous system generally acts to conserve resources and restore homeostasis, often with effects reciprocal to the sympathetic nervous system.Facial Nerve: The 7th cranial nerve. The facial nerve has two parts, the larger motor root which may be called the facial nerve proper, and the smaller intermediate or sensory root. Together they provide efferent innervation to the muscles of facial expression and to the lacrimal and SALIVARY GLANDS, and convey afferent information for TASTE from the anterior two-thirds of the TONGUE and for TOUCH from the EXTERNAL EAR.Cytoplasmic Granules: Condensed areas of cellular material that may be bounded by a membrane.Adrenal Glands: A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS.Salivary Gland Calculi: Calculi occurring in a salivary gland. Most salivary gland calculi occur in the submandibular gland, but can also occur in the parotid gland and in the sublingual and minor salivary glands.Sympathectomy: The removal or interruption of some part of the sympathetic nervous system for therapeutic or research purposes.Rats, Inbred Strains: Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions. This also includes animals with a long history of closed colony breeding.Parotid Region: The region of the face on either side, around the PAROTID GLAND.Trigeminal Nerve Diseases: Diseases of the trigeminal nerve or its nuclei, which are located in the pons and medulla. The nerve is composed of three divisions: ophthalmic, maxillary, and mandibular, which provide sensory innervation to structures of the face, sinuses, and portions of the cranial vault. The mandibular nerve also innervates muscles of mastication. Clinical features include loss of facial and intra-oral sensation and weakness of jaw closure. Common conditions affecting the nerve include brain stem ischemia, INFRATENTORIAL NEOPLASMS, and TRIGEMINAL NEURALGIA.Radiotherapy, Intensity-Modulated: CONFORMAL RADIOTHERAPY that combines several intensity-modulated beams to provide improved dose homogeneity and highly conformal dose distributions.Secretory Rate: The amount of a substance secreted by cells or by a specific organ or organism over a given period of time; usually applies to those substances which are formed by glandular tissues and are released by them into biological fluids, e.g., secretory rate of corticosteroids by the adrenal cortex, secretory rate of gastric acid by the gastric mucosa.Organ Sparing Treatments: Techniques, procedures, and therapies carried out on diseased organs in such a way to avoid complete removal of the organ and preserve the remaining organ function.Substance P: An eleven-amino acid neurotransmitter that appears in both the central and peripheral nervous systems. It is involved in transmission of PAIN, causes rapid contractions of the gastrointestinal smooth muscle, and modulates inflammatory and immune responses.Carcinoma, Adenoid Cystic: Carcinoma characterized by bands or cylinders of hyalinized or mucinous stroma separating or surrounded by nests or cords of small epithelial cells. When the cylinders occur within masses of epithelial cells, they give the tissue a perforated, sievelike, or cribriform appearance. Such tumors occur in the mammary glands, the mucous glands of the upper and lower respiratory tract, and the salivary glands. They are malignant but slow-growing, and tend to spread locally via the nerves. (Dorland, 27th ed)Secretory Vesicles: Vesicles derived from the GOLGI APPARATUS containing material to be released at the cell surface.Panniculitis, Lupus Erythematosus: A type of lupus erythematosus characterized by deep dermal or subcutaneous nodules, most often on the head, face, or upper arms. It is generally chronic and occurs most often in women between the ages of 20 and 45.Tuberculosis, Oral: Tuberculosis of the mouth, tongue, and salivary glands.Methenamine: An anti-infective agent most commonly used in the treatment of urinary tract infections. Its anti-infective action derives from the slow release of formaldehyde by hydrolysis at acidic pH. (From Martindale, The Extra Pharmacopoeia, 30th ed, p173)Muscarinic Agonists: Drugs that bind to and activate muscarinic cholinergic receptors (RECEPTORS, MUSCARINIC). Muscarinic agonists are most commonly used when it is desirable to increase smooth muscle tone, especially in the GI tract, urinary bladder and the eye. They may also be used to reduce heart rate.Tannins: Polyphenolic compounds with molecular weights of around 500-3000 daltons and containing enough hydroxyl groups (1-2 per 100 MW) for effective cross linking of other compounds (ASTRINGENTS). The two main types are HYDROLYZABLE TANNINS and CONDENSED TANNINS. Historically, the term has applied to many compounds and plant extracts able to render skin COLLAGEN impervious to degradation. The word tannin derives from the Celtic word for OAK TREE which was used for leather processing.Atropine: An alkaloid, originally from Atropa belladonna, but found in other plants, mainly SOLANACEAE. Hyoscyamine is the 3(S)-endo isomer of atropine.Microscopy, Electron: Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.Sebaceous Gland Neoplasms

Fine structure and cytochemistry of the intralobular ducts of the human parotid gland. (1/1132)

An intralobular duct of a human parotid gland has two parts, an intercalated part and a striated part. Intercalated ducts are lined with low cuboidal cells endowed with scanty cytoplasmic organelles. Striated ducts are lined with columnar cells rich in mitochondria and glycogen particles, and are characterized by extensive infoldings of the basal plasma membrane. The apical cytoplasm of the cells of the striated ducts shows a number of membrane-bound granules having a diameter of about 0-15 mum. These granules contain material of varying electron density which does not react with silver or with the histochemical reagents employed in the present study. Thus, on the basis of their small size and histochemical characteristics, they are distinct from the large and dense secretory granules observed in the so-called granular striated ducts of some animals. In addition, cells of striated ducts contain lysosomes, peroxisomes, and large lipoid bodies which give histochemical reactions typical of lipofuscins. Bodies of myoepithelial cells have been observed only in intercalated ducts. Their processes, however, extend into the proximal parts of striated ducts.  (+info)

Origin of acinar cell regeneration after atrophy of the rat parotid induced by duct obstruction. (2/1132)

Acinar cell regeneration in the rat parotid gland after atrophy induced by a one week period of duct obstruction was examined using histology, immunohistochemistry and transmission electron microscopy (TEM). For immunohistochemistry, antibodies to 5-bromo-2'-deoxyuridine (BrdU), injected one hour before tissue collection, and cytokeratin were employed. When clips were removed from the duct, only ductal epithelial cells remained; all acinar cells had been deleted. Some duct cells were BrdU positive. After three days, newly-formed acini comprising immature acinar cells had appeared; many of the cells were BrdU positive and mitotic figures were readily identified. Thereafter progressive acinar cell maturation and proliferation occurred, parotid gland weight returning to control levels by 7 days. Peak BrdU labelling indices for duct and acinar cells were on days 0 and 4, respectively. By TEM, cytoplasmic organelles in epithelial cells of transitional duct-acinar structures seen at 2 days were poorly developed. Immature acinar cells seen on day 3 contained zymogen granules and had increased endoplasmic reticulum and mitochondria. By day 5, maturing acinar cells had abundant endoplasmic reticulum and zymogen granules, resembling acinar cells in control glands. These observations indicated origin of acinar cell precursors from duct cells during regeneration of the acinar cell-free atrophic gland. Subsequent expansion of the acinar cell population was dependent on maturation and proliferation of these newly-formed cells.  (+info)

Secretion of old versus new exportable protein in rat parotid slics. Control by neurotransmitters. (3/1132)

The possibility that old and new secretory granules do not mix and that older exportable protein can be secreted preferentially was tested on parotid gland in vitro. Slices from fasted animals were pulse labeled for 3 min with L-[3H]leucine. Subcellular fractionstion showed that after 1 90-min chase period, the formation of new labeled secretory granules was mostly completed. The ratio of label in secretory granules to label in microsomes increased 250-fold during the period 5--90 min postpulse. After the 90-min chase, a submaximal rate of secretion was initiated by adding a low concentration of isoproterenol to the slices. Preferential secretion of old unlabeled exportable protein was evident from the finding that the percent of total amylase secreted was 3.5-fold greater than the percent of labeled protein secreted. Preferential secretion of old unlabeled exportable amylase was undiminished even when the chase period before addition of isoproterenol was extended to 240 min. Such long chase incubations were still meaningful due to the fact that the spontaneous rat of amylase release and radioactive protein release from the slices was negligibly low. A high isoproterenol concentration added to the slices after a 90-min chase produced the following results. An initial phase of preferential secretion of old unlabeled protein was soon replaced by secretion of a random mixture of new and old exportable protein. Electron micrographs indicated that high rates of secretion involved sequential fusion of secretory granules so that the lumen extended deep into the cell where the new labeled granules were presumably located. At low rates of secretion, the lumen showed no such deep extensions. Experiments were also conducted on slices from glands which had been largely depleted of old granules by prior injection of isoproterenol into the animals. Secretion of labeled protein from such slices stopped with the export of 80% of the labeled protein. This finding indicates that about 20% of the radioactive protein is cellular nonexportable protein and that the slices are capable of exporting the entire amount of secretory protein which was symthesized in vitrol. In addition to the beta-adrenergic receptor which mediates protein secretion, the parotid acinar cell also possesses an alpha-adrenergic and a cholinergic receptor both of which cause K+ release, vacuole formation, and water secretion. Activation of either of the latter two receptors in conjunction with the beta-adrenergic receptor increased randomization of the protein secreted. It is concluded that in the rat parotid acinar cell there is little spontaneous mixing between old granules near the luminal cell membrane and new granules coming up behind from the Golgi complex. The neurotransmitters which induce secretion produce the observed randomization.  (+info)

Ryanodine and inositol trisphosphate receptors are differentially distributed and expressed in rat parotid gland. (4/1132)

The present study examines the cellular distribution of the ryanodine receptor/channel (RyR) and inositol 1,4,5-trisphosphate receptor (InsP3R) subtypes in parotid acini. Using fluorescently labelled 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene-3-propionic acid glycyl-ryanodine (BODIPYtrade mark-ryanodine) and confocal microscopy, RyRs were localized primarily to the perinuclear region (basal pole) of the acinar cell. Ryanodine, Ruthenium Red, cAMP and cADP ribose (cADPR) competed with BODIPY-ryanodine, resulting in a reduction in the fluorescence signal. However, inositol 1,4, 5-trisphosphate [Ins(1,4,5)P3] did not alter the binding of BODIPY-ryanodine. Using receptor-subtype-specific antisera, InsP3Rs (types I, II and III) were located predominantly in the apical pole of the parotid cell. The presence of these three subtypes was confirmed using reverse transcriptase PCR with RNA-specific oligonucleotide probes. Binding studies using a parotid cell-membrane fraction identified and characterized RyRs and InsP3Rs in terms of binding affinity (Kd) and maximum binding capacity (Bmax) and confirmed that cADPR displaces ryanodine from its binding sites. Ruthenium Red and 8-Br-cADP-ribose blocked Ca2+ release in permeabilized acinar cells in response to cADPR and cAMP or forskolin, whereas Ins(1,4,5)P3-induced Ca2+ release was unaffected. The localization of the RyRs and InsP3Rs in discrete regions endow broad areas of the parotid cell with ligand-activated Ca2+ channels. The consequences of the dual activation of the RyRs and InsP3Rs by physiologically relevant stimuli such as noradrenaline (norepinephrine) are considered in relation to Ca2+ signalling in the parotid gland.  (+info)

Quantitative description of the spatial arrangement of organelles in a polarised secretory epithelial cell: the salivary gland acinar cell. (5/1132)

Previous quantitative descriptions of cellular ultrastructure have focused on spatial content (volume, surface area and number of organelles and membrane domains). It is possible to complement such descriptions by also quantifying spatial arrangements. Hitherto, applications of stereological methods for achieving this (notably, estimation of covariance and pair correlation functions) have been confined to organ and tissue levels. This study explores 3-dimensional subcellular arrangements of key organelles within acinar cells of rabbit parotid salivary glands, highly polarised epithelial cells specialised for exocrine secretion of alpha-amylase. It focuses on spatial arrangements of secretion product stores (zymogen granules), rough endoplasmic reticulum (RER) and mitochondria. Systematic random samples of electron microscopical fields of view from 3 rabbits were analysed using test grids bearing linear dipole probes of different sizes. Unbiased estimates of organelle volume densities were obtained by point counting and estimates of covariance and pair correlation functions by dipole counting. Plots of pair correlation functions against dipole length identified spatial arrangement differences between organelle types. Volumes within RER and mitochondrial compartments were positively correlated with themselves at distances below 4 microm and 2 microm respectively but were essentially randomly arranged at longer distances. In sharp contrast, zymogen granules were not randomly arranged. They were clustered at distances below 6-7 microm and more widely scattered at greater distances. These findings provide quantitative confirmation of the polarised arrangement of zymogen granules within acinar cells and further support for the relative invariance of biological organisation between subjects.  (+info)

Ultrastructure of the parotid gland in two species of naked-backed bats. (6/1132)

Naked-backed bats of the genus Pteronotus (family Mormoopidae) occur in the Neotropics from Mexico through northern South America. These are relatively small-sized insectivorous species that frequently roost in caves. Eight specimens of naked-backed bats (Pteronotus parnellii) were live-trapped in Suriname and one in Cuba (P. quadridens). Their parotid glands were fixed in an aldehyde mixture designed for field work and postfixed in the laboratory with osmium tetroxide. Tissues were further prepared for electron microscopy by conventional means. The parotid glands of the two species of Pteronotus closely resemble each other except for the substructure of their serous secretory granules. Serous granules in P. parnellii are bizonal, with a moderately dense inner matrix and an outer, denser corona or crescent. The matrix is occupied by laminae, flakes, and filaments in random array. In contrast, serous granules in P. quadridens consist of a uniform matrix that contains dense, usually stacked toroids or tubules either in random array or packed in bundles. A parotid gland from one specimen of P. parnellii contained an endpiece that consisted of cells that contained giant (up to 9 pm in diameter) serous granules. Serous cells in both species contain aggregates of small, uniformly dense, rod-like, membrane-delimited organelles as well as occasional bundles of cytofilaments. The endpieces are separated from intercalated ducts by a ring of granulated cells that contain secretory granules that often have a bull's-eye configuration. Intercalated and striated ducts are typical in appearance, except that many of the cells in the latter contain small, dense secretory granules in their apical cytoplasm. The parotid glands in the two species of naked-baked bats differ slightly in terms of acinar secretory granule ultrastructure, but otherwise are fairly conservative. It is thought that the glands in these particular bats might represent the "basal" condition of the salivary glands of insectivorous bats and thus can serve as a reference point for making comparisons to the highly diversified (in terms of diet) phyllostomid bats.  (+info)

Developmental changes of sugar residues and secretory protein in mucous cells of the early postnatal rat parotid gland. (7/1132)

Mucous cells have been identified in the terminal portions of the early postnatal parotid gland in human and rat, although mature parotid gland acini are composed of serous cells or seromucous cells. Previously, Ikeda et al. demonstrated that mucous cells are present in the rat parotid gland on days 1 to 8 after birth and that the secretory granules within these mucous cells share some histochemical characteristics with mature serous cells. However, it is still not clear whether the mucous cells change into serous cells as the gland develops. The purpose of this study was to determine whether the mucous cells that appear in the early postnatal rat parotid gland change into serous cells. Parotid glands were obtained from male or female Wistar rats (aged 0-14 days and adults). Fixed tissue sections were reacted with soybean agglutinin (SBA) and wheat germ agglutinin (WGA) to detect glycoconjugates, or were stained using an anti-neonatal submandibular gland protein B1 (SMG-B1) antibody to identify serous acinar cells. The sections were observed by transmission electron microscopy. Electron microscopy revealed that cells with characteristics intermediate between those of mucous and serous cells (transitional cells) appeared around day 8 and that the nuclei of these cells did not show chromatin condensation, a characteristic of apoptotic cells. Lectin histochemistry showed that the mucous cells had the same sugar residues as the serous cells, which appeared after day 10. Immunohistochemistry with an anti-SMG-B1 antibody gave a positive reaction not only in the cells with highly electron-dense granules but also in the electron-dense cores of bipartite or tripartite granules in the transitional cells. Cells with morphological characteristics intermediate between those of mucous and serous cells (transitional cells) appearing in the early postnatal rat parotid gland begin to produce B1-immunoreactive protein common to serous acinar cells during development of the gland.  (+info)

Isoproterenol potentiates alpha-adrenergic and muscarinic receptor-mediated Ca2+ response in rat parotid cells. (8/1132)

The effects of the cAMP pathway on the Ca2+ response elicited by phospholipase C-coupled receptor stimulations were studied in rat parotid cells. Although 1 microM isoproterenol (Iso) itself had no effect on the cytosolic Ca2+ concentration, the pretreatment with Iso potentiated Ca2+ responses evoked by phenylephrine. The potentiating effect of Iso was attributed to a shifting of the concentration-response curves of phenylephrine to the left and an increase in the maximal response. Half-maximal potentiation occurred at 3 nM Iso. Iso also potentiated the Ca2+ response elicited by carbachol. The potentiating effect of Iso was mimicked by forskolin (10 microM) and dibutyryl adenosine 3',5'-cyclic monophosphate (2 mM) and was blocked by 10 microM H-89. Iso potentiated the phenylephrine-induced Ca2+ response in the absence of extracellular Ca2+, but Iso did not increase the inositol trisphosphate (IP3) production induced by phenylephrine. These results suggest that the potentiation of the Ca2+ response can be attributed to a sensitization of IP3 receptors by cAMP-dependent protein kinase.  (+info)

Parotid gland - WikipediaParotid gland - Wikipedia
The parotid gland is a major salivary gland in many animals. In humans, the two parotid glands are present on either side of the mouth and in front of both ears. They are the largest of the salivary glands. Each parotid is wrapped around the mandibular ramus, and secretes serous saliva through the parotid duct into the mouth, to facilitate mastication and swallowing and to begin the digestion of starches. The word parotid (paraotic) literally means "beside the ear". The parotid glands are a pair of mainly serous salivary glands located below and in front of each ear canal, draining their secretions into the vestibule of the mouth through the parotid duct. Each gland lies behind the mandibular ramus and in front of the mastoid process of the temporal bone. The gland can be felt on either side, by feeling in front of each ear, along the cheek, and below the angle of the mandible. The gland is roughly wedge-shaped when seen from the surface. The parotid duct, a long excretory duct, emerges from the ...
Effects of extracellular ATP on ion transport systems and [Ca2+]i in rat parotid acinar cells. Comparison with the muscarinic...Effects of extracellular ATP on ion transport systems and [Ca2+]i in rat parotid acinar cells. Comparison with the muscarinic...
The effects of extracellular ATP on ion fluxes and the intracellular free Ca2+ concentration ([Ca2+]i) were examined using a suspension of rat parotid acinar cells and were contrasted with the effects of the muscarinic agonist carbachol. Although ATP and carbachol both rapidly increased [Ca2+]i about threefold above the resting level (200-250 nM), the effect of ATP was due primarily to an influx of Ca2+ across the plasma membrane, while the initial response to carbachol was due to a release of Ca2+ from intracellular stores. Within 10 s, ATP (1 mM) and carbachol (20 microM) reduced the cellular Cl- content by 39-50% and cell volume by 15-25%. Both stimuli reduced the cytosolic K+ content by 57-65%, but there were marked differences in the rate and pattern of net K+ movement as well as the effects of K+ channel inhibitors on the effluxes initiated by the two stimuli. The maximum rate of the ATP-stimulated K+ efflux (approximately 2,200 nmol K+/mg protein per min) was about two-thirds that of the ...
Two modes of regulation of the phospholipase C-linked substance-P receptor in rat parotid acinar cells | Biochemical JournalTwo modes of regulation of the phospholipase C-linked substance-P receptor in rat parotid acinar cells | Biochemical Journal
In rat parotid acinar cells prelabelled with [3H]inositol, substance P (100 nM) induced the formation of [3H]inositol 1,4,5-trisphosphate [Ins(1,4,5)P3]. Ins(1,4,5)P3 reached a maximum 7 s after substance P stimulation, and thereafter decreased and reached a stable value at 60 s. When the cells were exposed to substance P for 10, 30, 60, or 300 s, washed, and re-exposed to this peptide, the formation of [3H]inositol trisphosphate (InsP3) was attenuated in a time-dependent manner. In the cells pretreated as described above, the number of [3H]substance-P-binding sites (Bmax) was also decreased. Possible role(s) of Ca2+ and protein kinase (protein kinase C) control mechanisms in regulating substance P responses were investigated. Desensitization of substance P-induced InsP3 was not affected by the Ca2+ ionophore ionomycin, nor was it dependent on Ca2+ mobilization.

In the pig parotid gland, ATPDase was mainly associated with duct epithelium, with very little, if any, immunoreactivity on acinar cells. Myoepithelial cells dispersed among acini produced a significant signal. There have been reports of Ca2+-dependent ATPases associated with isolated parotid acinar cells, but as judged by their biochemical properties, these ATPases are different from ATPDases. However, a nucleoside triphosphatase described by Sato et al. (29) in bovine parotid gland and an apyrase described by Valenzuela et al. (34) in a microsomal fraction of rat salivary gland appear to correspond to the ATPDase described in this study and hence could well be associated with ductal epithelial and myoepithelial cells. In agreement with these findings, some studies on rat parotid acini show very little ecto-ATPase activity (9). Some P2Zpurinoceptors have been described on rat parotid acinar cells, which respond to ATP and mediate a Ca2+increase caused by both an influx and a mobilization from ...
Metabolism of inositol 1,4,5-trisphosphate and inositol 1,3,4-trisphosphate in rat parotid glands | Biochemical JournalMetabolism of inositol 1,4,5-trisphosphate and inositol 1,3,4-trisphosphate in rat parotid glands | Biochemical Journal
A complete separation of myo-inositol 1,4,5-[4,5-(32)P]trisphosphate prepared from human erythrocytes, and myo-[2-3H]inositol 1,3,4-trisphosphate prepared from carbachol-stimulated rat parotid glands [Irvine, Letcher, Lander & Downes (1984) Biochem. J. 223, 237-243], was achieved by anion-exchange high-performance liquid chromatography. This separation technique was then used to study the metabolism of these two isomers of inositol trisphosphate in carbachol-stimulated rat parotid glands. Fragments of glands were pre-labelled with myo-[2-3H]inositol, washed, and then stimulated with carbachol. At 5s after stimulation a clear increase in inositol 1,4,5-trisphosphate was detected, with no significant increase in inositol 1,3,4-trisphosphate. After this initial lag however, inositol 1,3,4-phosphate rose rapidly; by 15s it predominated over inositol 1,4,5-trisphosphate, and continued to rise so that after 15 min it was at 10-20 times the radiolabelling level of the 1,4,5-isomer. In contrast, after ...

OBJECTIVES. Primary Objective:. Feasibility will be defined as 80% of volunteers achieving detectable signal changes in pre/post salivary MR images (in either the IVIM or the DCE scans).. BACKGROUND INFORMATION AND RATIONALE. It is well known that loss of salivary function in the parotid glands leads to an elevated risk of chronically dry-mouth. Xerostomia is thought to result from salivary function loss due to damage of the functional aspects of the (saliva-producing) parotid gland, but the precise nature is unknown. Recent reports have found regional dose susceptibility in rat parotid(1); delivering dose to one region of the parotid results in a different incidence of xerostomia than would that same dose to another region. Similarly, regional dose susceptibility of subjective xerostomia (i.e. patient-reported) has been noted in human parotid(2). It is presently unclear to what extent these findings relate to objective functional loss, recovery, or xerostomia in humans. With this motivation, ...

Rat parotid glands express M2 and M3 mAChRs; the M3 mAChRs represent 90% of the total number of precipitable mAChRs (Ehlert et al., 1996). As shown in Fig. 1, M3 mAChR activation by ACh or pilocarpine increases AQP5 levels in the APM of rat parotid cells. The M3 mAChR-stimulated increases of AQP5 in the APM was inhibited by treatment of the tissues with U73122, TMB-8, and dantrolene (Ishikawa et al., 2000), indicating that M3 mAChRs activate PLC, increase the release of Ca2+ via the activation of IP3 and ryanodine receptors, and induce an increase in AQP5 levels in the APM. M3 mAChR stimulation also induces the generation of DAG and leads to PKC activation. The M3 mAChR-stimulated increase of AQP5 in the APM, however, was not inhibited by treatment with GF 109203X (Ishikawa et al., 2000), indicating that PKC did not regulate the amount of AQP5 in the APM.

.Objectives: To measure phosphorus metabolites in human parotid glands by 31P-MRS using three-dimensional chemical-shift imaging (3D-CSI), and ascertain whether this method can capture changes in adenosine triphosphate (ATP) and phosphocreatine (PCr) levels due to saliva secretion. Study Design: The parotid glands of 20 volunteers were assessed by 31P-MRS using 3D-CSI on 3T MRI. After obtaining a first (baseline) measurement, the participants took vitamin-C tablets and measurements were obtained twice more, in a continuous manner. The peak area ratios of PCr and β-ATP were evaluated. Results: A high proportion of PCr (0.26 ± 0.08) and ATP (α: 0.16 ± 0.06; β: 0.27 ± 0.06; γ: 0.21 ± 0.03) was noted at baseline.

Studies show that a dose response relationship in the salivary glands exists and that it may be possible to improve significantly post-radiation xerostomia and quality of life if radiation techniques can be devised that would spare the salivary glands while adequately treating the targets. A new treatment modality (computer-optimized IMRT) facilitates increased sparing of noninvolved tissue, specifically the sparing of both parotid glands, and more conformal high-dose delivery to the bilateral neck targets in patients with head and neck cancer. This study will evaluate the benefits regarding xerostomia-specific and general QOL in patients receiving head and neck RT using this modality. Assessment of swallowing dysfunction and aspiration will be made using videofluoroscopy. In addition, this study will evaluate the pattern of local/regional tumor recurrence, to assess whether sparing both parotid glands may cause tumor recurrence in spared neck areas ...

When this nitrite-rich saliva gets swallowed into acidic gastric juics, it converts into nitric oxide (NO), reducing inflammation throughout the body. Chewing also stimulates the parotid glands, behind the ears in the jaw, to release hormones that stimulate the thymus to produce T cells, which are the core of the protective immune system. Healthy teeth and gums are critical for proper digestion. Many people eat so fast, they barely chew their food at all and then wash it down with liquids. That means the stomach receives chunks of food instead of mush. When my son, Arthur, was seven years old, he demonstrated this by eating upside-down. ) Absorption occurs when digested food molecules are taken through the epithelial cell lining of the small intestine into the bloodstream and through the portal vein to the liver, where they are filtered. From the bloodstream they pass to the cells. Until food is absorbed, it is essentially outside the body-in a tube going through it. If the gut is inflamed, as ...

Parotidectomy | UC Irvine Medical CenterParotidectomy | UC Irvine Medical Center
Parotidectomy is a surgery performed to remove either a small portion or the entire parotid gland. The parotid glands are located under the skin in front of the ear overlying the jaw bone. Most commonly a parotidectomy is performed to remove a mass or lump within the gland, or to remove the gland in cases of recurrent stones or infections. The parotid gland is closely associated with the facial nerve which controls movements of the face such as raising the eyebrow and smiling. As such parotidectomy is a very challenging surgery, in which removal of the gland must be balanced with preserving the facial nerve. Prior to surgery a surgeon, in the case of a mass or lump, the surgeon may perform order a CT or MRI exam to help determine the anatomy of the parotid gland.. Parotidectomy is performed in the operating room under general anesthesia. A cut is made on the skin around the ear, similar to the incisions used during a face-lift. The facial nerve is identified as it enters the salivary gland and ...
Parotidectomy - WikipediaParotidectomy - Wikipedia
A parotidectomy is the surgical excision (removal) of the parotid gland, the major and largest of the salivary glands. The procedure is most typically performed due to neoplasms (tumors), which are growths of rapidly and abnormally dividing cells. Neoplasms can be benign (non-cancerous) or malignant (cancerous). The majority of parotid gland tumors are benign, however 20% of parotid tumors are found to be malignant. A parotidectomy is performed mostly by the oral and maxillofacial surgeons and otolaryngologist. There are two parotid glands in the human body. Each parotid gland is located high in the neck just below the ears. A salivary duct by which saliva is secreted (produced and released), runs through the inside of each cheek from each gland. Furthermore, the extratemporal (outside temporal bone) facial nerve and its subsidiaries run through the parotid gland and innervate (supply nerves to) the face. This nerve articulates the muscles for facial expression as well as more specific muscles ...

Cyclic antidepressants are still a dominating group of psychotherapeutic drugs used in the treatment of depression. Dry mouth is one of their major side effects. In this study we analyzed the effects of the long-term administration of the tricyclic antidepressant desipramine and the reversibility of this treatment following a 15-day washout period on different parameters in parotid gland function in aging rats. We hypothesized that glandular function would be decreased, and recovery delayed with age. Drug treatment affected body weight, glandular weight, DNA synthesis, and the concentration of soluble and structural membrane proteins. Surprisingly, parotid flow rate was increased with desipramine in all ages. While the concentration of secreted proteins was generally decreased with treatment, total proteins secreted were quite stable. SDS/PAGE analysis revealed prominent changes with desipramine. Amylase activity was depressed with treatment, but only low residual cellular enzyme activity was ...

To assess the impact of intensity modulated radiotherapy (IMRT) versus conventional radiation on late xerostomia and Quality of Life aspects in head and neck cancer patients. Questionnaires on xerostomia in rest and during meals were sent to all patients treated between January 1999 and December 2003 with a T1-4, N0-2 M0 head and neck cancer, with parotid gland sparing IMRT or conventional bilateral neck irradiation to a dose of at least 60 Gy, who were progression free and had no disseminated disease (n = 192). Overall response was 85% (n = 163); 97% in the IMRT group (n = 75) and 77% in the control group (n = 88) the median follow-up was 2.6 years. The prevalence of complaints was compared between the two groups, correcting for all relevant factors at multivariate ordinal regression analysis. Patients treated with IMRT reported significantly less difficulty transporting and swallowing their food and needed less water for a dry mouth during day, night and meals. They also experienced fewer problems

Third, the tissues examined in the two studies differed: Delli et al used sequential parotid biopsies, whereas we performed labial MSG biopsies. Except for the group from Gröningen, very few groups worldwide routinely use parotid biopsy, which requires the intervention of a trained surgeon. The differences between these two tissue types is ill-defined.14 The presence of lymphoepithelial lesions is more commonly observed in parotid tissue than in labial MSG; parotid tissue may contain physiological lymphoid tissue between lobules, including lymphoid follicles even in healthy individuals; and parotid acini are purely serous whereas in labial MSG acini are both mucinous and serous. A theoretical advantage of parotid biopsy is that the same gland can be analysed sequentially. However, it seems that the analysis of sequential biopsies of the same gland is not reproducible over time, as illustrated by the apparent variability (in terms of number of lymphoepithelial lesions, relative area of ...

Fractionated irradiation of salivary glands : loss and protection of functionFractionated irradiation of salivary glands : loss and protection of function
Radiotherapy of malignancies in the head and neck often involves the major and minor salivary glands in the radiation field. Adverse effects, such as dry mouth symptoms, are common after such therapy. The aim of this thesis was to study longitudinal effects of fractionated irradiation to the head and neck on salivary gland function in man and in the rat and to test radioprotection from antioxidant vitamins (retinol, a-tocopherol and ^-carotene).. A sharp decrease in parotid saliva flow rate was seen after one week of irradiation in cancer patients, but in some patients recovery was seen two months after completed treatment. Loss and recovery of salivary gland function were dependent on the total dose given. Irradiation with doses of ,65 Gy to the parotid glands led to permanent loss of function in the majority of parotid glands, while recovery could be seen after irradiation with doses of ,52 Gy. Concentrations of some proteins and electrolytes in saliva were increased during irradiation but no ...

ERV can be put to physiological use by their hosts, either at the gene regulatory level or as proteins. Tissue-specific enhancers in the ERV LTR are an example of transcriptional control. All mammals express amylase in the pancreas, but rodents and Old World primates also express amylase in salivary glands. In both the cases, ERV elements play a role in salivary expression in remarkably convergent evolution. The activation of salivary amylase in the human parotid gland is controlled by a retroviral insertion, which occurred during Old World primate evolution [54]. Then gene triplication of the amylase gene and its LTR enhancer to further enhance amylase secretion occurred after hominids split from chimpanzees. It may have provided selective advantage to the hominid lineage when, like rodents, they adopted a diet containing complex carbohydrates.. Many years ago, it was noted that MLV is not transcriptionally active in murine embryonal carcinoma stem cells, but that during differentiation into ...

The ability of foetal rat salivary epithelium, particularly from the parotid gland, to develop morphogenetically and functionally (amylase activity) in various mesenchymes, and the quantitative effects of altering mesenchymal mass on the development of the parotid epithelium, have been studied in vitro.. Both parotid and submandibular epithelial rudiments were able to undergo morphogenesis and subsequent cytodifferentiation in their own and in the reciprocal mesenchyme. The growth of the explant and the arrangement of the acini were governed by the mesenchyme, submandibular mesenchyme supporting the development of more acini, which were more closely packed, than parotid mesenchyme. The functional product of the epithelium was not qualitatively affected, amylase activity being developed only by parotid epithelium, whether in its own or in submandibular mesenchyme.. Amylase activity was greater when the epithelium from a single parotid rudiment was recombined with submandibular mesenchyme than ...

Part or all of the face may be weak or paralyzed. To treat a parotid tumor, part or all of the gland is removed. This surgery is called parotidectomy. This sheet explains the surgery and what to expect.

Carcinoma of the Parotid Gland… they took out 34 Lymph nods from my left neck and removed the Parotid Gland and my Salivary Duct Gland and my entire Neck Muscle. Dr. McCaffery said he believes he got it all and I have clean edges. There is a .08 cm nogle on my right Lung but they dont know what this is since its to small to tell. So they want to keep a close eye on this. They want me to do Radiation which Im not sure I want to do. They want to do the Radiation to take care of any micro cells they cannot see. Im not sure I want to do radiation, as far as I understand Im Cancer Free but like I said they want to do Radiation to kill the micro cells and they do not want me to take anything that has Anti Oxidants, they said this would interfere with the Free Radicals. I was taking Protandim, Intra Max, Nature Doc - SuperSulfur CBD Oil, and recently started to ad Franken scent to my water and juices..

Facial Surgery/ENT - Edge Neuro MonitoringFacial Surgery/ENT - Edge Neuro Monitoring
Surgery in ear, nose and throat (ENT) medicine is delicate, complex and high-precision. This is also the case for surgery of the parotid (parotid gland surgery). During parotid surgery, the location of the facial nerve branches poses a major challenge to the surgeon. Monitoring, localization and function-testing of nerves located in the operating field is instrumental in supporting the surgeon during the parotid procedure.. Intraoperative neuromonitoring serves as a method of choice, delivering lower risks and an improved patient outcome. The most common ENT interventions in which the C2 NerveMonitor is used are:. ...

Abstract. The oral cavity is a moist environment, a film of fluid called saliva constantly coats its inner surfaces and occupies the space between the lining oral mucosa and the teeth. Saliva is a complex fluid, pro-duced by the salivary glands, whose important role is maintaining the wellbeing of the mouth. Patients with a deficiency of salivary secretion experience difficulty eating, speaking, swallowing as well as become prone to mucosal infections and rampant caries. In human there are three pairs of major encap-sulated salivary glands - (parotid, submandibular, and sublingual). Located outside the oral cavity, with extended duct systems to discharge their secretion. There are also a multitude of smaller minor unen-capsulated salivary glands. (labial, lingual, palatal, buccal, glossopalatine and retromolar). Located just below and within the mucous membranes, characterized by short duct systems. Secretion of each major salivary gland is not the same, the parotid glands secrete a rich amylase ...

Dream Mom: Dear Son Blenderized Diet & UpdateDream Mom: Dear Son Blenderized Diet & Update
Aside from the blenderized diet, he overall is doing well except for some severe choking. Dear Sons throat muscles have deteriorated with is progressive disease and he is unable to process his own secretions. Normal people swallow their own saliva throughout the day but he cant swallow (which is why he uses a feeding tube) so he is choking on his own saliva. We have tried the normal treatments of Robinul and even botox injections in 2008 for him but they both failed. We had been using a Scopolamine patch for many years up until the manufacturing shortage. Once we stopped the patch, we learned that it was actually causing seizures for Dear Son. When we tried the patch after the manufacturing issue was resolved, we could tell that it was causing seizures for him so now we cant use that. We met with an ENT to discuss the possibility of the removal of his submandibular glands and one of his parotid glands. I thought perhaps since Dear Son was healthy, this might be a good time to consider this ...

Beastie Boys Adam MCA Yauch RIP | Cancer Survivors NetworkBeastie Boys' Adam MCA Yauch RIP | Cancer Survivors Network
Hi jtl. Im a bit of an odd case to be honest - I did have a node involved but it was removed in the belief it was a branchial cyst. After they found MEC I have had a recent selective dissection to check if it had spread and all the other nodes were clean. So Im free of node involvement now. My difference is there is no primary to be found; Ive had PET, CT, MRI and nothing. They took a tonsil and section from my BOT with the dissection to try to find it as those are hiding places from PET because of the other activity but nothing, all clear.. Also usually PET finds cancer in the major parotid gland very easily but no sign there either. They have two theories - firstly that the original tumor might have actually been the primary as you can find salivary glands in nodes. Second my immune system may have dealt with the primary. Aside from all the surgery Ive had no treatment and am just having 4 monthly scans now for 12 months.. My onc says with the nodes now sorted, the grade and the primary if ...

Chloraphil?? More like Bore-a-phil!: Benign is the greatest french sounding word in the English LanguageChloraphil?? More like Bore-a-phil!: Benign is the greatest french sounding word in the English Language
A few months ago Kym started having blackouts. Shed lose vision for a few seconds, then be ok. After seeing the doctors a few times they ordered a cat scan. They found clogged sinuses, which is most likely the cause when combined with low blood pressure. But they also found pollups on her parotid gland. They ordered an MRI on that, where they found a tumor on her thyroid. The tumor has calcification, and with the help of google, we found some wonderful studies that told us that means there is an 80% chance the tumor is cancer. On Monday she had all three lumps biopsied. The results were released to the doctor yesterday and after about 10 calls and 24 brutal hours of waiting they called back, and we found all results are benign. One of the pollups showed benign results, but there was a limited sample so they want to do it again. Which sucks, but its a thousand million times better than the way we felt a few days ago ...
Beastie Boys Adam Yauch RememberedBeastie Boys' Adam Yauch Remembered
For most fans, Adam Yauchs death came as a surprise. We had known of his diagnosis and treatment for cancer of parotid gland since the summer of 2009, but updates since then had varied, but mainly positive, ranging from claiming that he had "beat cancer" to "reports… are exaggerated" to "Hes doing OK," so to learn that the Beastie Boys MCA had died last Friday at the young age of 47 was a hard blow. Far less surprising, though, has been the immediate outpouring of grief, support for his friends and family, and inspiring memories that surfaced through innumerable tributes and remembrances on all forms of media. For a band that started as a trio of noisy party brats to evolve into the thoughtful and revered godfathers of rap they have become is truly a unique phenomenon in the music industry and testifies to the endearing nature of the Beastie Boys themselves. And of the three, Adam Yauch was the most outspoken when it came to influencing how we think about others, whether it was his public ...

  • Benign ectopic thyroid tissue within the parotid salivary gland is very rare. (smj.org.sg)
  • The possible origin of the ectopic thyroid tissue in the parotid salivary gland could be due to a common evolution of the thyroid and parotid glands, a heteroplasia or a metaplasia. (smj.org.sg)
  • This is due to normal function of parotid remaining tissue and can find a way out of the wound or collect under the skin forming a cyst around the scar in about 2-5% of the cases. (georgalas.org)

Lesions3
Nerve13
  • General Sensory innervation to the parotid gland, its sheath, and the overlying skin is provided by the great auricular nerve. (wikipedia.org)
  • Postganglionic sympathetic fibers from superior cervical sympathetic ganglion reach the gland as periarterial nerve plexuses around the middle meningeal artery and their function is mainly vasoconstriction. (wikipedia.org)
  • There, they synapse with postganglionic fibers which reach the gland by hitch-hiking via the auriculotemporal nerve, a branch of the mandibular nerve. (wikipedia.org)
  • A mimic of craniofacial pain symptoms of Ernest Syndrome and stylomandibular ligament injury, ACC in this case presented with ear, jaw and tooth pain, as well as pain on chewing and opening wide-all as a result of a growing mass affecting the trigeminal nerve with perineural invasion, the carotid artery, and the parotid gland. (practicalpainmanagement.com)
  • The morphological structure and the neuropeptide-containing nerve fibers (NPY, GAL, SOM, SP, CGRP, VIP) of the glands were examined by light and electronmicroscopy. (elsevier.com)
  • It is suggested that the hypertrophic changes in the glands might be caused by the alterations of nerve fibres. (elsevier.com)
  • These nerves grow back, however a nerve that supplied the salivary gland may grow into and supply sweat gland and vice versa. (facialsurgery.ie)
  • Therefore when the patient smells or tastes food, the nerve fires but stimulates the sweat gland instead of the salivary gland. (facialsurgery.ie)
  • It is caused by injury to a nerve, called the auriculotemporal nerve, typically after surgical trauma to the parotid gland. (urlikes.co)
  • The parasympathetic secretomotor fibres to parotid arises from the glossopharyngeal nerve. (medicoapps.rocks)
  • The nerve reaches the gland via tympanic branch, the lesser petrosal nerve, the otic ganglion and the auriculotemporal nerve. (medicoapps.rocks)
  • From the auriculotemporal nerve, but the parotid fascia is innervated by the sensory fiberes of the great auricular nerve. (medicoapps.rocks)
  • This nerve runs within the gland and injury to the nerve may result in partial paralysis of that part of the face. (drsethi.com.sg)
Lobe of the parotid gland4
  • The tumor involving the deep lobe of the parotid gland demonstrates an inhomogeneous mild degree of enhancement ( large arrow ). (ajnr.org)
  • The superficial lobe of the parotid gland contained numerous well-circumscribed masses protruding from its surface and multiple homogeneous 0.5- to 1.0-cm nodules throughout the gland parenchyma ( Fig 2 A ). One of the nodules showed central necrosis, corresponding to the imaging findings. (ajnr.org)
  • We report 2 interesting cases of hydatid cysts in unusual sites: in the breast and the deep lobe of the parotid gland. (scielo.org.za)
  • On excision, the cyst appeared to extend into the deep lobe of the parotid gland. (scielo.org.za)
