what are the muscles of mastication and what are they innervated by

masseter, temporalis, lateral and medial pterygoid innervated by V3 branches

what are the MATT muscles innervated by v3 branches?

mylohyoid, anterior belly digastric, tensor veli palatini, tensor tympani

which muscles are produced by the 1st pharyngeal arch and innervated by v3?

mastication and MATT

which muscles arise from the 2nd pharyngeal arch and are innervated by facial

post belly of digastric, stylohyoid, stapedius

what is the action of the masseter muscle?

elevates, protrudes the jaw, deep fibers retried the chin, occlude teeth for biting and chewing

what are some clinical considerations with the masseter muscle?

muscle transfers, nerve transfers, aesthetic procedures

what is the action of temporalis muscle

elevates mandible (closes jaw), retrusion (retraction) of the mandible (pulls jaw backwards)

what are temporalis transfers

temporalis has long fibers that can be transferred over or under the zygomatic arch for facial reanimation

lateral pterygoid function

protrude the mandible, side to side movement

medial pterygoid action

elevate and protrude the mandible, side to side action

what is the TEMPORAL MANDIBULAR JOINT

a synovial joint with an articular disk with auriculotemporal innervation for sensory

it is a hinge and sliding joint

what is an eminectomy

osteotomy of the articular eminence, performed to manage recurrent mandibular dislocatiion and helps to make a non-reducing disk a reducing disk

what is the pterygopalatine fossa

it is a neurovascular hub containing pterygopalatine ganglion which delivers sympathetics to lacrimal gland and nasal/sinus mucosal

what is a sphenopalatine ganglion block associated with?

it is associated with the trigeminal nerve involved in headache disorders, trigeminal neuralgia, and idiopathic facial pain
