FOM 2 Week 2 Flashcards
Branches of V
V1- opthalmic
V2- maxillary
V3- mandibular
nerves of ear
facial auricular branch
vagus auricular branch
TM- V3 (main), X, VII
to zandibar by motor car
branches of facial nerve
temporal
zygomatic
buccal
marginal mandibular
cervical
path of glossopharyngeal nerve, parasympathetic pathway
glossopharyngeal branches to tympanic nerve to lesser petrosal nerve, synapses in otic ganglion then to parotid branches
layers of SCALP
skin
dense connective tissue
aponeurosis
loose connective tissue (danger area)
pericranium
parotitis
inflammation and swelling of parotid gland due to virus, bacteria, or obstruction
all the muscles meet at the corner of the the mouth is called
modiolius
IT fossa pathway
IT fossa (room) to pterygomaxillary fissure (door frame) to pterygopalatine fossa (hallway) to sphenopalatine (door frame) to nasal cavity (room)
temporalis
elevate mandibule, retract mandible
medial and lateral pterygoid
medial pterygoid- elevate and protrude mandible
lateral pterygoid- protracts mandible, swings jaw toward contralateral side
maxillary 1st part, enter skull
middle meningeal artery- supplies dura and calvaria, enters skull via foramen spinosum
inferior alveolar artery- feeds lower teeth, gingivae, mandible, mouth
provides branch to mylohyoid muscle
enters mandible via mandibular foramen near lingula and runs within mandibular canal
terminates mental artery exiting out mental foramen
maxillary 3rd part, follows nerves
sphenopalatine artery
descending palatine artery
infraorbital artery
retromandibular vein divisions
anterior goes to IJV
posterior goes to EJV
comes from pterygoid plexus to maxillary vein to retromandibular vein
TMJ movements hinge close mouth
temporalis, massester, medial pterygoid
TMJ movement hinge open mouth
graveity, lateral pterygoid, suprahyoid/infrahyoid
