what are the 4 cranial nerves
maxillary branch of the trigeminal n (GSA)
greater and lesser petrosal n fo the facial n, GVE, SVA
pharyngeal plexus, SVE, GSA
-CN IX,X
what is the anterior 2/3’s of the tongue innervated by and the components?
lingual n of V3 and the chorda tympani n
SVA
this is the part of the tongue that separates the anterior 2/3s of tongue and posterior third?
sulcus terminalis
what is the posterior 1/3 of the tongue innervated by? components?
CN IX
GSA,GVE, SVA
this is the part of the tongue that is located in between the palatopharyngeal fold and epiglottis? what is the innervation and components?
root of the tongue
vagus nerve (GSA,SVA)
this type of papilla is not associated with taste buds?

this type of papilla is mushroom shaped?
fungiform papilla
this type of papilla is fold like?
foliate papilla
this type of papilla is big and round; found in the back of the tongue near the sulcus terminalis?
vallate papilla
what are the muscles of the tongue innervated by? intrinsic muscles innervation? extrinsic muscle innervation?
CN XII except palatoglossus; within the belly of the tongue, innervated by CN XII; so again, like in the first question the innervations are CN XII, except palatoglossus m innervated by CN X
what are the extrinsic muscles of the tongue?
styloglossus m
hyoglossus m
genioglossus m
palatoglossus m
what’s the arterial supply of the tongue?
