what is cranial nerve I?
what nerve is responsible for smell?
what is cranial nerve II?
what nerve is responsible for sight?
cranial nerve II or optic nerve
which side of the optic nerve crosses over to the opposite side?
severing what area would result in the loss of sight in the medial portion of each eye?
what is cranial nerve III?
what nerve innervates the levator palpebrae?
external strabismus is a malfunction of which cranial nerve?
name all of the things that is a malfunction of the oculomotor nerve?
drooping of the upper eyelid (ptosis), external strabismus, abnormal dilation of the pupil, loss of power of accommodation and slight bulging of the eyeball due to relaxed eye muscles
what cranial nerve constrict the pupil or innervated muscles to change the shape of the lens for focusing?
oculomotor or cranial nerve III
what is bitemporal hemianopia?
blindness in the temporal field of vision in both eyes
pressure or trauma to what nerve can cause loss of function in the same side of the head as the injury?
oculomotor nerve or cranial nerve III
what cranial nerve innervate one of the extrinsic muscle that controls downward and lateral movement of the eyeball?
trochlear nerve or cranial nerve IV
what is the smallest of the twelve cranial nerve?
what happens when the trochlear nerve becomes paralyzed?
cause loss of function in the superior oblique so that one is unable to turn his eye outward and downward
irritation of what nerve may cause spasms of one of the muscles supplied by it?
what is cranial nerve V?
what is cranial nerve V's motor function?
innervates muscle of massification
what is the nerve that's sensory function are involved in sensation of touch, temperature and pain from specific regions of the face
what is the largest nerve of the twelve?
cranial nerve V
what are the symptoms if the sensory root of cranial nerve V was damages? (5)
anesthesia of half of the face on the side damaged, dryness of the nose, loss of sensation to anterior 2/3 of tongue, and inflammation/irritation to the nerve, intense, pulsating pain
what would happen if the cranial nerve V's motor function was damaged?
impaired action of the lower jaw due to paralysis of muscles of mastication of the affected side
what is cranial nerve VI?
what nerve is more frequently involved in fractures of the base of the skull than any other cranial nerve?
what happens when the abducens nerve is injured?
partial or complete paralysis of the external rectus muscle and a certain amount of dilation in one of the pupils
what may a certain amount of dilation in one of the pupils indicated?
swelling and pressure in the brain
what nerve moves the eye laterally?
what is cranial nerve VII?
what is the motor function of the facial nerve?
innervate several muscles of facial expression and to stimulate the salivary glands
what is the sensory function of the facial nerve?
receives impulses from the anterior portion of the tongue and convey them to the gustatory (taste) areas of the insula
what cranial nerve is associated with sublingual and submandibular glands?
facial nerve or cranial nerve VII
what cranial nerve is more frequently paralyzed than any of the twelve cranial nerves?
cranial nerve VII
what cranial nerve causes Bell's Palsy?
