temporal and infratemporal fossae Flashcards
4 muscles of mastication?
temporalis, masseter, lateral pterygoid, medial pterygoid
major artery of the infratemporal fossae?
maxillary artery => learn all the branches and where they go
pterygomaxillary fissure contains?
ptergypalatine fossa for the pterygpalatine ganglion, it has a spot for greater petrosal n. and deep petrosal n.
branch of maxillary to deep face?
after it passes through the sphenopalatine foramen. sphenopalatine artery.
temporalis m attaches?
origin @ temporal fossa to coronoid process of mandible
medial pterygoid attaches? action?
goes from medial part of the lateral plate to the angle of mandible. moves jaw laterally
lateral pterygoid attaches?
right next to the TMJ on the pterygoid fovea and the articular disk
scaphoid fossa
where medial pterygoid m attaches
foramen ovale has
auriculotemporal nerve that wraps around the middle meningial artery (which is a branch of the maxillary a)
greater palatine branches go across to?
they come through the palatine foramina. they pass anteriorly to the hard palate. the Smaller branch goes to the Soft palate
review: what pharyngeal arch makes the pterygoid fovea
second arch. Meckel’s cartilage
mylohyoid groove for?
nerve to mylohyoid m.
mental spines for?
genioglossus m and geniohyoid m. (innervated by C1)
lingular ligament?
sphenomandibular ligament covers the inferior alveolar nerve (gives off nerve to mylogyoid) and inferior alveolar artery
where are the four articular disks?
two in TMJ, two in sternoclavicular joint
if someone has TMJ, what nerve relays pain?
auriculotemporal, auriculotemporal, masseteric nerves
if you close your mouth, what muscles do yo use?
temporalis, masseter, medial pterygoid
muscles that protrude the chin?
lateral pterygoid, masseter and medial pterygoid
review: fascia over lateral aspect of head?
temporalis fascia
review: sensory nerve to cheek
buccal n., anterior to the lingual nerve (v3)
how does chordae tympani get to its final destination
comes through the foramen ovale with the inverior alveolar nerve(v3) and takes a little detour over to the lingual nerve
where is the otic ganglion?
it sits right next to v3 inferior to the foramen ovale
buccinator m. mastication?
NO!!!!! its innervated by VII
what muscle uses the hamulus as a fulcrum?
tensor veli palatini m. it is lateral to the levator veli palatini m.
four branches of the first maxillary artery section
look up
five branches of the second maxillary artery section
look up
branches of the third maxillary artery section
look up
components of motor V3
SVE
squamotympanic fissure has what arteries?
anterior tympanic, deep auricular
foramen for middle meningeal a.
foramen spinosum
foramen for accessory meningeal
foramen ovale
veins of this area?
pterygoid venous plexus and communicate to cavernous sinus, into internal jugular v,
tissue layers of the cheek?
skin, buccal fat pad, buccinator m, buccal mucosa
where would you put your chew?
oral vestibule
there are 32 what?
adult teeth
what CNs for taste? their ganglia?
VII (geniculate ganglion), IX(inferior ganglion), X (inferior ganglion of vagus). these are all SVA fibers
muscles of the tongue by CN XII
these are “extrinsic mm of the tongue” genioglossus, hyoglossus, styloglossus
the only muscle not innervated by CN XII?
palatoglossus m. its CN X
as CN VII it goes where
posterior to mylohyoid and anterior to hyoglossus
lower jaw dental procedure, you should numb up the
inferior alveolar n.
