Tempora, infratemporal region Flashcards
what vv goes through the parotid gland
superficial temporal
retroman vv formed from
junction of the superficial temporal and maxillary vv
interesting feature of the vv of the angular region
possess no valves, can drain to cavernous sinus
what splits the parotid into superficial and deep?
CN VII
what vv is in the parotid gland?
retroman vv
ciliary ganglion
location
fibers from?
targets?
in the orbit
parasym from CN 3 (pregang fibers)
sym from the superior cervical plexus (postgang fibers)
targets the sphincter papillae and lens for accomodation
pterygopalatine ganglion
location
fibers from?
targets?
located in pterygopalatine fossa
parasym from greater petrosal nn of CN 7 (pregang)
sym from superior cervical plexus (postgang)
targets lacrimal and nasal glands
otic ganglion
location
fibers from?
targets?
between tensor palatini veli and the mandibular nn
parasym fibers from tympanic nn of CN 9 (pregang)
sym from the superior cervical plexus
targets the parotid gland
submandibular ganglion
location
fibers from?
targets?
located on surface of hyoglossus mm
parasym from chroda tympani of CN 7 (pregang)
sym from superior cervical plexus
targets the subman and sublingual gland
anterior to the ext auditory meatus?
mandibular condyle
Ear pain can often be from what dental pathology? inn of area
TMJ, but TMJ pain could be associated with ear abnormality
inn of the area is very complex: CN’s 5,7,9, and 10 all present
ligaments of TMJ
fibrous capsule
lat ligament
stylomandibular ligament
sphenomandibular ligament
TMJ opening
two parts
initally just simple hinge and rotation within the mandibular fossa
further opening results in anterior movement of the condyle/articular disc
sensation of TMJ
lots from CN V but other nn contribute too
articular disc of TMJ
divides the sup/inf portions of the joint capsule
pathway of CN 9 contribution to otic ganglion
will send preganglionic parasym to typnaic plexus in the tympanic cavity (tympanic nn)
then projects as lesser petrosal nn to the otic ganglion for synapse
importance of the lingula
mandibular foramen on other side of it>where the inf alveolar nn will enter
lingual nn also moves alongside it
sphenomandibular ligament attatches here
nn of the man condyle
all from CN V3 deep temporal auriculotemporal masserteric lots of inn means lots of pain with any inflammation
aa lateral to the TMJ
superficial temporal Aa
eutaschian/ pharyngotympanic tube
allows ears to adjust to pressure changes
tube from the nasal cavity to the ears
movements of the mandible
protrusiuon retraction elevation depression rotation
mm that form a sling for the mandible
massetter and medial pterygoid
mm for mandible elevation
temporalis
massetter
med pterygoid
mm for mandible depression
lat pterygoid (pulls forward/down) suprahyoid/infrahyoid mm
