cranial nerves and innervations Flashcards
three branches of the trigeminal nerve
opthalmic, maxillary, mandibular
what does the mandibular branch go thru
oval foramen
what nerve supplies sensory to the cheek mucosa
buccal n of the mandibular (V)
what provides motor to the cheek, facial expression
dorsal and ventral buccal
only innervation to the lacrimal gland
VII, thru the auriculopalpebral n
what nerves travel through the internal acoustic meatus
CN VII, VIII
where does CN VII exit the skull
stylomastoid foramen
taste and pain sensation to the rostral part of the tongue
taste: VII, caudal tempany
pain: V, lingual
caudal sensation and taste of tongue
glossopharyngeal, IX
what are the mastication muscles innervated by?
V3 mandibular, and VII- caudal digastricus m
sensation to the chin?
mental nerve, V3
sensory to the lower teeth
inferior alveolar, V3
auriculotemporal vs auriculopalpebral?
auriculotemporal: V3 sensory branch to temple/rostral ear
auriculopalpebral is branch of facial n. close eyelids.
innervation to the parotid salivary gland
glossopharyngeal IX.
sole innervation to the larynx
vagus
what is the muscle that opens the mouth in mastication
digastricus
innervation to tensor veli palatini?
levator veli palatini?
tensor: V3
levator: IX, X
what does the levator vlei palatini over lay from the medial view?
pterygopharyngeus m
main drainer ln of the ox head
lateral retropharyngeal
there is one dilator of the pharynx. who innervates it?
stylopharyngeus caudalis. IX
what innervates the constrictors of the pharynx
IX, X
parotid duct runs the risky route in what species?
dogs and sheeps
ventral buccal runs the safe route in what species?
bovine
