crainial nerve functions (bio exam 4)

sensory for smell

sensory for vision

sensory for proprioception from muscles served

motor to 4 of 6 extrinsic eye muscles which are responsible for movement of the eyeball:
superior rectus
Medial rectus
inferior rectus
inferior oblique

motor to "levator palpebrae superioris" which opens the upper eyelid

motor to intrinsic eye muscle "ciliary muscle" which changes shape of lens for near or far vision- accommodation

motor to sphincter muscle of iris which changes size of pupil controlling amount of light (only constriction)

sensory for proprioception of muscle innervated

motor to the "superior oblique" extrinsic muscle of the eye involved in movement of eyeball

motor to muscles of mastifcation- control chewing

sensory from face,mouth, and teeth for touch, pain, and temperature

motor to the "lateral rectus" extrinsic muscle of the eye involved in movement of eyeball

Motor to facial, scalp, and neck muscles involved in facial expressions

motor to lacrimal and salivary glands- stimulaes secretion of saliva and tears

sensory for taste from the anterior 2/3rds of tongue

sensory for hearing and equilibrium

sensory for taste from posterior 1/3rd of tongue

sensory from carotid sinus for regulation of blood pressure

motor to swallowing muscles of pharynx

motor to parotid gland- stimulates salivation

sensory and motor innervating most viscera, pharyngeal and laryngeal muscles for swallowing, laryngeal muscles for speech, heart and lungs, smooth muscle of digestive tract, taste buds of throat

motor for muscles involved in swallowing

motor to trapezius and sternoclleidomastoid- therefore coordinates head movements

motor to tongue muscles- involved in tongue movements for speech and swallowing
