morning questions Flashcards
what structures fill the gap between the skull and superior constrictor muscle
the pharyngeobasilar fascia
nerve that is sensory to the piriform recess
internal branch of superior laryngeal (vagus)
relationship between levator veli palatini to the torus tubarius?
torus is the end of the tube, and the salpingopharyngeal fold comes off at the end of the tube. the answer is inferior
what structures form the pillars of the tonsils
palatopharyngeal, palatoglossal folds
artery is located in the gap between the inferior and middle constrictors
glossopharyngeal n. runs through here. there are a few arteries that run through here, but the most important is the tonsilar branch of the facial artery
germ layer gives rise to the mucosa of the hard palate
the maxillary processes come down and make the shelves that form the roof of your mouth. also, think about what nerve innervates that area. trigeminal, PHA 1, its ECTODERM
frontonasal process is derived from
mesenchymal tissue
innervation of styloglossus
XII
hypoglossal nerve goes between what two muscles
mylohyoid, hyloglossus
what functional deficits from a tumor located in internal acoustic meatus?
this is CN VII and VIII … the entire nerve so facial palsy on the whole side of the face. Dry eye, hearing loss, lack of taste on anterior 2/3 of tongue, dry mouth from submandibular sublingual glands (cordae tympani), posterior auricular n. sensory loss on ear, maybe some dysphagia, nostagmus
what functional components associated with superior laryngeal n.
branch of X that splits internal branch :GVAexternal branch : SVE
tympanic nerve functional components
CN IX: sensory to middle ear GVA. lesser petrosal has pregang psy so GVE
lingual nerve near mylohyoid line functional components
this nerve, V3, already picked up the chordae tympani, so it has SVA, GSA, GVE
superior root of ansa cervicalis functional components
upper strap muscles = GSE
deep temporal nerve functional components
V3 muscle of mastication: SVE (first pharyngeal arch)
what bone(s) make eustacian tube?
temporal
what bone(s) make tuberculum sellae
sphenoid
what bone(s) make carotid canal
temporal
relationship of CN XII to hyoglossus
anterior to the hyoglossus and posterior to myohyoid
relationship of inferior thyroid a. to the common carotid a.
behind the carotid sheath… so posterior.
what strx goes through the sphenopalatine foramen
sphenopalatine a from maxillary system
what strx wraps around the pterygoid hamulus
tensor villi palatini (innervated by V3)
what strx passes through the inferior orbital fissure
V2, kinda; infraorbital a. these two come together and go out the infraorbital foramen*** I would also add inferior opthalmic v.
retrogradely label pterygopalatine ganglion. where are the labeled cell bodies?
greater petrosal nerve (VII) from brainstem. also symp. pass through here. their cell bodies in sup. cervical ganglion
