  • obstructive
  • In a patient with characteristic signs of obstructive MGD, slit-lamp microscopy reveals meibomian gland orifices that are closed with plugs consisting of thickened, opaque secretions containing keratinized material with telangiectasia around the orifice and lid margin rounding. (arvojournals.org)
  • fluids
  • Foul-smelling fluids typically are released from this gland when snakes are molested, thus inspiring the frequent suggestion that these secretions repel predators. (degruyter.com)
  • orifice
  • Snakes (order Squamata, suborder Serpentes) possess a paired exocrine organ, called the scent gland, situated in the base of the tail and opening through two ducts at the margin of the cloacal orifice. (degruyter.com)
  • male
  • Analysis by gas chromatography/mass spectrometry of the scent gland secretions of male and female Middle American burrowing pythons ( Loxocemus bicolor ) revealed the presence of over 300 components including cholesterol, fatty acids, glyceryl monoalkyl ethers, and alcohols. (degruyter.com)
  • study
  • Polymorphous low-grade adenocarcinoma of minor salivary glands: a study of 14 cases of a distinctive neoplasm. (ac.ir)
  • Treatment
  • We describe a rare case of PLGA of the parotid gland in a teenager with its clinical characteristics, histopathological features, and treatment. (ac.ir)
  • Hormones
  • The secretory activities of the gland cells and the contractions of myoepithelial cells are controlled by both the autonomic nervous system and by the circulating hormones. (wikipedia.org)
  • Parathyroid hormone and calcitonin (one of the hormones made by the thyroid gland) have key roles in regulating the amount of calcium in the blood and within the bones. (wikipedia.org)
  • These glands often secrete hormones, and play an important role in maintaining homeostasis. (wikipedia.org)
  • Each gland has an outer cortex which produces steroid hormones and an inner medulla. (wikipedia.org)
  • Salt gland activations occurs from increased osmolarity in the blood, stimulating the hypothalamic information processing, sending signal through the parasympathetic nerve activating vasodilation, the release of hormones (acetylcholine and vasoactive intestinal peptide). (wikipedia.org)
  • epithelial
  • Parathyroid glands are derived from the epithelial lining of the third and fourth pharyngeal pouches, with the superior glands arising from the fourth pouch, and the inferior glands arising from the higher third pouch. (wikipedia.org)
  • Exocrine glands are glands that produce and secrete substances onto an epithelial surface by way of a duct. (wikipedia.org)
  • Every gland is formed by an ingrowth from an epithelial surface. (wikipedia.org)
  • In compound glands the more typical or secretory epithelium is found forming the terminal portion of each branch, and the uniting portions form ducts and are lined with a less modified type of epithelial cell. (wikipedia.org)
  • They develop from epithelial buds in the sulcus surrounding the sublingual folds on the floor of the mouth, lateral to the developing submandibular gland. (wikipedia.org)
  • An electrical gradient is formed from the chloride ions, allowing sodium to be passed through the tight junctions of the epithelial cells into the salt gland along with minimal amounts of water. (wikipedia.org)
  • posterior
  • The posterior pituitary (or neurohypophysis) is a lobe of the gland that is functionally connected to the hypothalamus by the median eminence via a small tube called the pituitary stalk (also called the infundibular stalk or the infundibulum). (wikipedia.org)
  • The parathyroid glands are variable in number: three or more small glands, and can usually be located on the posterior surface of the thyroid gland. (wikipedia.org)
  • The gland can be bilaterally palpated (felt) inferior and posterior to the body of the mandible, moving inward from the inferior border of the mandible near its angle with the head tilted forwards. (wikipedia.org)
  • esophagus
  • The cardiac glands are found in the cardia of the stomach which is the part nearest to the heart, enclosing the opening where the esophagus joins to the stomach. (wikipedia.org)
  • eccrine
  • Eccrine sweat glands are distributed almost all over the human body, in varying densities, with the highest density in palms and soles, then on the head, but much less on the trunk and the extremities. (wikipedia.org)
  • Non-primate mammals have eccrine sweat glands only on the palms and soles. (wikipedia.org)
  • They have eccrine glands between hairs over most of their body (while humans have them between the hairs on their scalp ). (wikipedia.org)
  • seromucous
  • The seromucous glands are found primarily in the anterior nasal cavity, and they are also found within the nasal cavity. (wikipedia.org)
  • Anterior lingual glands (also called apical glands) are deeply placed seromucous glands that are located near the tip of the tongue on each side of the frenulum linguae. (wikipedia.org)
  • outer
  • Exocrine glands secrete their products through a duct onto an outer surface of the body, such as the skin or the gastrointestinal tract. (wikipedia.org)
  • Placing one index finger within the mouth and the fingertips of the opposite hand outside it, the compressed gland is manually palpated between the inner and outer fingers. (wikipedia.org)
  • mucosa
  • The anterior nasal glands help moisturize the nasal mucosa. (wikipedia.org)
  • Submucosal means that the actual gland resides in the connecting tissue below the mucosa. (wikipedia.org)
  • The gastric mucosa is pitted with innumerable gastric pits which house the gastric glands. (wikipedia.org)
  • They are fewer in number than the other gastric glands and are more shallowly positioned in the mucosa. (wikipedia.org)
  • Olfactory glands, also known as Bowman's glands are situated in the olfactory mucosa, beneath the olfactory epithelium, in the lamina propria, a connective tissue also containing fibroblasts, blood vessels, and bundles of fine axons from the olfactory neurons. (wikipedia.org)
  • upper eyelid
  • There are usually 2 to 5 of these glands in the upper eyelid, and their function is to produce tears which are secreted onto the surface of the conjunctiva. (wikipedia.org)
  • There are approximately forty Krause glands in the region of the upper eyelid, and around 6 to 8 in the region of the lower lid. (wikipedia.org)
