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.[2]. 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.[2]. ...
