Temporal Muscle: A masticatory muscle whose action is closing the jaws; its posterior portion retracts the mandible.Masticatory Muscles: Muscles arising in the zygomatic arch that close the jaw. Their nerve supply is masseteric from the mandibular division of the trigeminal nerve. (From Stedman, 25th ed)Masseter Muscle: A masticatory muscle whose action is closing the jaws.Mastication: The act and process of chewing and grinding food in the mouth.Pterygoid Muscles: Two of the masticatory muscles: the internal, or medial, pterygoid muscle and external, or lateral, pterygoid muscle. Action of the former is closing the jaws and that of the latter is opening the jaws, protruding the mandible, and moving the mandible from side to side.Decompressive Craniectomy: Excision of part of the skull. This procedure is used to treat elevated intracranial pressure that is unresponsive to conventional treatment.Bite Force: The force applied by the masticatory muscles in dental occlusion.Jaw: Bony structure of the mouth that holds the teeth. It consists of the MANDIBLE and the MAXILLA.Muscles: Contractile tissue that produces movement in animals.Mandible: The largest and strongest bone of the FACE constituting the lower jaw. It supports the lower teeth.Muscle Neoplasms: Tumors or cancer located in muscle tissue or specific muscles. They are differentiated from NEOPLASMS, MUSCLE TISSUE which are neoplasms composed of skeletal, cardiac, or smooth muscle tissue, such as MYOSARCOMA or LEIOMYOMA.Cephalometry: The measurement of the dimensions of the HEAD.Muscle Proteins: The protein constituents of muscle, the major ones being ACTINS and MYOSINS. More than a dozen accessory proteins exist including TROPONIN; TROPOMYOSIN; and DYSTROPHIN.Dura Mater: The outermost of the three MENINGES, a fibrous membrane of connective tissue that covers the brain and the spinal cord.Muscle, Smooth: Unstriated and unstriped muscle, one of the muscles of the internal organs, blood vessels, hair follicles, etc. Contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei. Smooth muscle fibers are bound together into sheets or bundles by reticular fibers and frequently elastic nets are also abundant. (From Stedman, 25th ed)Muscle Fibers, Skeletal: Large, multinucleate single cells, either cylindrical or prismatic in shape, that form the basic unit of SKELETAL MUSCLE. They consist of MYOFIBRILS enclosed within and attached to the SARCOLEMMA. They are derived from the fusion of skeletal myoblasts (MYOBLASTS, SKELETAL) into a syncytium, followed by differentiation.Muscle, Skeletal: A subtype of striated muscle, attached by TENDONS to the SKELETON. Skeletal muscles are innervated and their movement can be consciously controlled. They are also called voluntary muscles.Electromyography: Recording of the changes in electric potential of muscle by means of surface or needle electrodes.Muscle, Smooth, Vascular: The nonstriated involuntary muscle tissue of blood vessels.Muscle Development: Developmental events leading to the formation of adult muscular system, which includes differentiation of the various types of muscle cell precursors, migration of myoblasts, activation of myogenesis and development of muscle anchorage.Muscle Contraction: A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.Muscle Fibers, Fast-Twitch: Skeletal muscle fibers characterized by their expression of the Type II MYOSIN HEAVY CHAIN isoforms which have high ATPase activity and effect several other functional properties - shortening velocity, power output, rate of tension redevelopment. Several fast types have been identified.Myringoplasty: Surgical restoration of a perforated tympanic membrane by grafting. (Dorland, 28th ed.)Muscle Fibers, Slow-Twitch: Skeletal muscle fibers characterized by their expression of the Type I MYOSIN HEAVY CHAIN isoforms which have low ATPase activity and effect several other functional properties - shortening velocity, power output, rate of tension redevelopment.Muscle Fatigue: A state arrived at through prolonged and strong contraction of a muscle. Studies in athletes during prolonged submaximal exercise have shown that muscle fatigue increases in almost direct proportion to the rate of muscle glycogen depletion. Muscle fatigue in short-term maximal exercise is associated with oxygen lack and an increased level of blood and muscle lactic acid, and an accompanying increase in hydrogen-ion concentration in the exercised muscle.Muscle Denervation: The resection or removal of the innervation of a muscle or muscle tissue.Neck: The part of a human or animal body connecting the HEAD to the rest of the body.Abscess: Accumulation of purulent material in tissues, organs, or circumscribed spaces, usually associated with signs of infection.Peritonsillar Abscess: An accumulation of purulent material in the area between the PALATINE TONSIL and its capsule.Pleural Cavity: Paired but separate cavity within the THORACIC CAVITY. It consists of the space between the parietal and visceral PLEURA and normally contains a capillary layer of serous fluid that lubricates the pleural surfaces.Retropharyngeal Abscess: An accumulation of purulent material in the space between the PHARYNX and the CERVICAL VERTEBRAE. This usually results from SUPPURATION of retropharyngeal LYMPH NODES in patients with UPPER RESPIRATORY TRACT INFECTIONS, perforation of the pharynx, or head and neck injuries.Ludwig's Angina: Severe cellulitis of the submaxillary space with secondary involvement of the sublingual and submental space. It usually results from infection in the lower molar area or from a penetrating injury to the mouth floor. (From Dorland, 27th ed)Thyroiditis, Suppurative: Acute inflammatory disease of the THYROID GLAND due to infections by BACTERIA; FUNGI; or other microorganisms. Symptoms include tender swelling, FEVER, and often with LEUKOCYTOSIS.Trigeminal Neuralgia: A syndrome characterized by recurrent episodes of excruciating pain lasting several seconds or longer in the sensory distribution of the TRIGEMINAL NERVE. Pain may be initiated by stimulation of trigger points on the face, lips, or gums or by movement of facial muscles or chewing. Associated conditions include MULTIPLE SCLEROSIS, vascular anomalies, ANEURYSMS, and neoplasms. (Adams et al., Principles of Neurology, 6th ed, p187)Trigeminal Nerve: The 5th and largest cranial nerve. The trigeminal nerve is a mixed motor and sensory nerve. The larger sensory part forms the ophthalmic, mandibular, and maxillary nerves which carry afferents sensitive to external or internal stimuli from the skin, muscles, and joints of the face and mouth and from the teeth. Most of these fibers originate from cells of the TRIGEMINAL GANGLION and project to the TRIGEMINAL NUCLEUS of the brain stem. The smaller motor part arises from the brain stem trigeminal motor nucleus and innervates the muscles of mastication.Neuralgia, Postherpetic: Pain in nerves, frequently involving facial SKIN, resulting from the activation the latent varicella-zoster virus (HERPESVIRUS 3, HUMAN). The two forms of the condition preceding the pain are HERPES ZOSTER OTICUS; and HERPES ZOSTER OPHTHALMICUS. Following the healing of the rashes and blisters, the pain sometimes persists.Nerve Compression Syndromes: Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.Neuralgia: Intense or aching pain that occurs along the course or distribution of a peripheral or cranial nerve.Rhizotomy: Surgical interruption of a spinal or cranial nerve root. (From Dorland, 28th ed)Microvascular Decompression Surgery: Surgery performed to relieve pressure from MICROVESSELS that are located around nerves and are causing NERVE COMPRESSION SYNDROMES.Myalgia: Painful sensation in the muscles.Operating Rooms: Facilities equipped for performing surgery.Dictionaries, MedicalDictionaries as Topic: Lists of words, usually in alphabetical order, giving information about form, pronunciation, etymology, grammar, and meaning.Dictionaries, ChemicalVena Cava, Inferior: The venous trunk which receives blood from the lower extremities and from the pelvic and abdominal organs.Sciatic Nerve: A nerve which originates in the lumbar and sacral spinal cord (L4 to S3) and supplies motor and sensory innervation to the lower extremity. The sciatic nerve, which is the main continuation of the sacral plexus, is the largest nerve in the body. It has two major branches, the TIBIAL NERVE and the PERONEAL NERVE.Terminology as Topic: The terms, expressions, designations, or symbols used in a particular science, discipline, or specialized subject area.Sphenoid Bone: An irregular unpaired bone situated at the SKULL BASE and wedged between the frontal, temporal, and occipital bones (FRONTAL BONE; TEMPORAL BONE; OCCIPITAL BONE). Sphenoid bone consists of a median body and three pairs of processes resembling a bat with spread wings. The body is hollowed out in its inferior to form two large cavities (SPHENOID SINUS).Scapula: Also called the shoulder blade, it is a flat triangular bone, a pair of which form the back part of the shoulder girdle.Ischium: One of three bones that make up the coxal bone of the pelvic girdle. In tetrapods, it is the part of the pelvis that projects backward on the ventral side, and in primates, it bears the weight of the sitting animal.Gingival NeoplasmsWingCranial Fossa, Middle: The compartment containing the anterior extremities and half the inferior surface of the temporal lobes (TEMPORAL LOBE) of the cerebral hemispheres. Lying posterior and inferior to the anterior cranial fossa (CRANIAL FOSSA, ANTERIOR), it is formed by part of the TEMPORAL BONE and SPHENOID BONE. It is separated from the posterior cranial fossa (CRANIAL FOSSA, POSTERIOR) by crests formed by the superior borders of the petrous parts of the temporal bones.Cerebral Ventricle Neoplasms: Neoplasms located in the brain ventricles, including the two lateral, the third, and the fourth ventricle. Ventricular tumors may be primary (e.g., CHOROID PLEXUS NEOPLASMS and GLIOMA, SUBEPENDYMAL), metastasize from distant organs, or occur as extensions of locally invasive tumors from adjacent brain structures.

The buccal nerve (long buccal nerve) is a nerve in the face. It is a branch of the mandibular nerve (which is itself a branch of the trigeminal nerve) and transmits sensory information from skin over the buccal membrane (in general, the cheek) and from the second and third molar teeth. Not to be confused with the buccal branch of the facial nerve which transmits motor information to the buccinator muscle. It courses between the two heads of the lateral pterygoid muscle, underneath the tendon of the temporalis muscle, and then under the masseter muscle to connect with the buccal branches of the facial nerve on the surface of the buccinator muscle. Small branches of the buccal nerve innervate the lateral pterygoid muscle. It also gives sensory branches to the cheek. The facial ...
The pterygoid plexus (/ˈtɛrɪɡɔɪd/; from Greek pteryx, "wing" and eidos, "shape") is a venous plexus of considerable size, and is situated between the temporalis muscle and lateral pterygoid muscle, and partly between the two pterygoid muscles. It receives tributaries corresponding with the branches of the maxillary artery. Thus it receives the following veins: sphenopalatine middle meningeal deep temporal (anterior & posterior) pterygoid masseteric buccinator alveolar some palatine veins (palatine vein which divides into the greater and lesser palatine v.) a branch which communicates with the ophthalmic vein through the inferior orbital fissure infraorbital vein This plexus communicates freely with the anterior facial vein; it also communicates with the cavernous sinus, by branches through the foramen Vesalii, foramen ovale, and foramen lacerum. Due to its ...
... (MMM) is an inflammatory disease in dogs affecting the muscles of mastication (chewing). It is also known as atrophic myositis or eosinophilic myositis. MMM is the most common inflammatory myopathy in dogs. The disease mainly affects large breed dogs. German Shepherd Dogs and Cavalier King Charles Spaniels may be predisposed. There is a similar disease of the eye muscles found in Golden Retrievers. Symptoms of acute MMM include swelling of the jaw muscles, drooling, and pain on opening the mouth. Ophthalmic signs may include third eyelid protrusion, red eyes, and exophthalmos (protruding eyeballs). In chronic MMM there is atrophy of the jaw muscles, and scarring of the masticatory muscles due to fibrosis may result in inability to open the mouth (trismus). The affected muscles include the ...
The word "templar" as used in anatomy has a separate etymology from the word temple, meaning "place of worship". Both come from Latin, but the word for the place of worship comes from templum, whereas the word for the part of the head comes from Vulgar Latin *tempula, modified from tempora, plural form ("both temples") of tempus, a word that meant both "time" and the part of the head. Due to the common source with the word for time, the adjective for both is "temporal" (both "pertaining to time" and "pertaining to the anatomical temple"). Regarding the temporalis muscle: in English, this muscle's name is the time muscle. As above, the word "temporalis" comes from the Latin word "tempus" meaning "time". The muscle covers the temporal bone, or time bone, which received its ...
The pterygomandibular space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space in the head and is paired on each side. It is located between the medial pterygoid muscle and the medial surface of the ramus of the mandible. The pterygomandibular space is one of the four compartments of the masticator space. The boundaries of each pterygomandibular space are: the posterior border of the buccal space anteriorly the parotid gland posteriorly the lateral pterygoid muscle superiorly the inferior border of the mandible (lingual surface) inferiorly the medial pterygoid muscle medially (the space is superficial to medial pterygoid) the ascending ramus of the mandible laterally (the space is deep to the ramus of the mandible) the communications of each pterygomandibular space are: to the buccal space anteriorly to the lateral ...
... is the positional relationship of the mandible or maxilla to the skeletal base where either of the jaws protrudes beyond a predetermined imaginary line in the coronal plane of the skull. In general dentistry, oral and maxillofacial surgery and orthodontics, this is assessed clinically or radiographically (cephalometrics). The word prognathism derives from Greek pro ("forward") and γνάθος gnáthos ("jaw"). One or more types of prognathism may result in the common condition of malocclusion, in which an individual's top teeth and lower teeth do not align properly. Prognathism in humans can be due to normal variation among phenotypes. In human populations where prognathism is not the norm, it may be a malformation, the result of injury, a disease state or a hereditary condition. Prognathism is considered a disorder only if it affects mastication, speech or social function as a byproduct of severely affected aesthetics of the face. Clinical determinants include soft tissue analysis ...
The medial pterygoid plate (or medial pterygoid lamina) of the sphenoid bone is a horse-shoe shaped process that arises from its underside. It is narrower and longer than the lateral pterygoid plate and curves lateralward at its lower extremity into a hook-like process, the pterygoid hamulus, around which the tendon of the tensor veli palatini glides. The lateral surface of this plate forms part of the pterygoid fossa, the medial surface constitutes the lateral boundary of the choana or posterior aperture of the corresponding nasal cavity. Superiorly the medial plate is prolonged on to the under surface of the body as a thin lamina, named the vaginal process, which articulates in front with the sphenoidal process of the palatine and behind this with the ala (wing) of the vomer. The angular prominence between the posterior margin of the vaginal process and the medial border of the scaphoid fossa is named the pterygoid tubercle, and immediately above this is the posterior opening of the pterygoid ...

The artery of the pterygoid canal (Vidian artery) is an artery in the pterygoid canal, in the head. It usually arises from the external carotid artery, but can arise from either the internal or external carotid artery or serve as an anastomosis between the two. The eponym, Vidian artery, is derived from the Italian surgeon and anatomist Vidus Vidius. In this case; the artery passes backward along the pterygoid canal with the corresponding nerve. It is distributed to the upper part of the pharynx and to the auditory tube, sending into the tympanic cavity a small branch which anastomoses with the other tympanic arteries. It can end in the oropharynx. In this case; the artery passes backward along the pterygoid canal with the corresponding nerve[clarification needed]. It The artery is a small, inconstant branch which passes into the pterygoid canal and anastomoses with a pterygopalatine branch of the maxillary artery. Nerve of pterygoid canal This article incorporates text in the public domain from ...
Its fibers pass downward, lateral, and posterior, and are inserted, by a strong tendinous lamina, into the lower and back part of the medial surface of the ramus and angle of the mandible, as high as the mandibular foramen. The insertion joins the masseter muscle to form a common tendinous sling which allows the medial pterygoid and masseter to be powerful elevators of the jaw. ...
The lateral surface of the great wing of the sphenoid is convex, and divided by a transverse ridge, the infratemporal crest, into two portions.. The superior or temporal portion, convex from above downward, concave from before backward, forms a part of the temporal fossa, and gives attachment to the Temporalis; the inferior or infratemporal, smaller in size and concave, enters into the formation of the infratemporal fossa, and, together with the infratemporal crest, affords attachment to the Pterygoideus externus.. ...
The medial masseter is enlarged, and passes through an enlarged infraorbital foramen to originate on the side of the rostrum. The superficial masseter originates on the front edge of the zygoma, and the lateral masseter extends over most of its length.. This condition is found throughout the suborders Hystricomorpha and Anomaluromorpha. In the suborder Myomorpha, it is found in the superfamily Dipodoidea and some fossil Muroidea (such as Pappocricetodon). Hystricomorphy is also found in the African dormouse Graphiurus, which is a member of the suborder Sciuromorpha.. ...
