olfactory nerve
purely sensory; carries impulses for the sense of smell
optic nerve
purely sensory; carries impulses for vision
oculomotor
supplies motor fibers to four of the six muscles (superior, inferior, and medial rectus, and inferior oblique) that direct the eyeball; to the eyelid; and to the internal eye muscles controlling lens shape and pupil size
trochlear
supplies motor fibers for one external eye muscle (superior oblique)
trigeminal
conducts sensory impulses from the skin of the face and mucose of the nose and mouth; also contains motor fibers that activate the chewing muscles
abducens
supplies motor fibers to the lateral rectus muscle, which rolls the eye laterally
facial
activates the muscles of facial expression and the lacrimal and salivary glands; carries sensory impulses from the taste buds of anterior tongue
vestibulocochlear
purely sensory; vestibular branch transmits impulses for the snese of balance and cochlear branch transmits impulses for the sense of hearing
glossopharyngeal
supplies motor fibers to the pharynx (throat) that promote swallowing and saliva production; carries sensory impulses from taste buds of the posterior tongue and from pressure receptiors of the carotid artery
vagus
fibers carry sensory impulses from and motor impulses to the pharnyx, layrnx, and the abdominal and thoracic viscera; most motor fibers are parasympathetic fibers that promote digestive activity and help regulate heart activity
accessory
mostly motor fibers that activate the sternocleidomastoid and trapezius muscles
hypoglossal
motor fibers control tongue movements; sensory fibers carry impulses from the tongue
