undefined, object
copy deck
purely sensory- carries afferent impulses associated w/ sense of smell
purely sensory- carries afferent impulses associated w/ vision
primarily motor- somatic motor fibers to inferior oblique and superior, inferior, and medial rectus muscles, which direct the eyeball, and to levator palpebrae muscles of the superior eyelid; parasympathetic fibers to iris and smoot muscle controlling lens shape
primarily motor- probides somatic motor fibers to superior oblique muscle
Mixed- major sensory nerve of face; conducts sensory impulses from skin of face and anterior scalp, from mucosae of mouth and nose, and from surface of the eyes; madibular division also contains motor fibers that innervate muscles of mastication and muscle of floor of mouth
carries motor fibers to lateral rectus of the eye
mixed (primarily motor in function) carries somatic motor fibers to tongue muscles
Mixed- supplies somatic motor fibers to muscles of facial expression and parasympathetic motor fibers of lacrimal and salivary glands; carries sensory fibers from taste receptors of anterior portion of the tongue
purely sensory- vestibular branc transmits impulses accociated w/ equillibrium from vestibular apparatus and semicircular canals; cochlear branch transmits impulses associated w/ hearing from the cochlea
mixed- somatic motor fibers serve pharyngeal muscles, and parasympathetic motor fibers serve salivary glands; sensory fibers carry impulses from pharynx, tonsils, posterior tongue (taste buds) and chemoreceptor and pressure receptors of the carotid artery
mixed- fibers carry somatic motor impulses to pharynx and larynx and sensory fibers from same structures; vary large porion is composed of parasympathetic motor fibers which supply heart and smooth muscles of abdominal visceral organs; transmits sensory impulses from viscera
mixed- but primarily motor in function- provides somatic motor fibers to sternocleidomastoid and trapezius muscle and to muscles of the soft palate, pharynx, and larynx (spinal and medullary fibers respectively)
