Cranial Nerves Flashcards
CN 1
olfactory nerve - supplies area of nose and has special sensory function of smell
CN II
optic nerve - special sensory - allows vision from retina
CN III
occulomotor nerve - supplies muscles around (outside) eyeball. muscle movements of eye e.g moves it up down, side to side
CN IV
trochlear nerve - supplies one single muscle (superior oblique) which moves eye down and outwards
CN V
trigeminal - 3 branches motor and sensory functions
CN V1
opthalmic branch of trigeminal - general sensory of cornea, skin of forehead, scalp , eyelids and nose
CN V2
maxillary branch of trigeminal - general sensory of upper lip, maxillary teeth and sinuses
CN V3
mandibular branch of trigeminal nerve - motor function to muscles of mastication , general sensory to sides of mandible, mandibular teeth, mucosa of mouth and anterior 2/3 of tongue
CN VI
Abducents nerve - supplies one single muscle (lateral rectus) - moves eye outwards and away from nose
LR6 SO4
lateral rectus = 6, superior oblique = 4, rest of eye muscle = 3
CN VII
facial nerve - supplies muscles of facial expression, taste to anterior 2/3 of tongue, supplies submandibular and sublingual salivary
what gland does CN VII run through
parotid gland
CN VIII
vestibulocochlear nerve - responsible for hearing and balance
CN IX
glossopharyngeal nerve
- somatic motor to stylopharyngeus (moves pharynx up)
- parasympathetic innervation to parotid gland
- taste to posterior 1/3 of tongue
CN X
vagus nerve - rest and digest
abdominal organs, required for swallowing and talking
