How many pairs of cranial nerves are there?

• 10
• 11
• 12
• 13

What nerve conducts sensory impulses from the skin of the face and mucosa of the nose and mouth and contains motor fibers that activate chewing muscles? *largest of all the cranial nerves and responsible for moving facial muscles by chewing and facial sensations. Try to remember Trident gum for chewing

• Vagus

• Trochlear

• Trigeminal

• Abducens

What nerve activates the muscles of facial expression and the lacrimal and salivary glands? produces tears, allows for taste, form facial expressions, saliva production

• Facial

• Vagus

• Accessory

• Optic

What nerve is purely sensory and transmits impulses for the sense of balance and sense of hearing? auditory (remember this by the word cochlear…think of cochlear implants that allow people to hear)

• Olfactory

• Optic

• Hypoglossal

What nerve is where fibers carry sensory impulses from and motor impulses to the pharynx, larynx, and the abdominal viscera ?

• Vestibulocochlear

• Accessory

• Facial

What nerve is mostly motor fibers that activate the sternocleidomastoid and trapezius muscles? allows head and shoulders movement and allows for swallowing

• Vestibulocochlear

• Accessory

• Vagus

• Facial

What nerve supplies motor fibers for one external eye muscle? moves eyeballs

• Vestibulocochlear

• Trochlear

• Glossopharyngeal

• Facial

What nerve supplies motor fibers to four of the extrinsic eye muscles that direct the eyeball, the eyelid, and control lens shape and pupil size? moves eyelids, rotates eyeballs, adjust pupils and lens of the eye (oculo deals with the eye and motor mean movement)

• Optic

• Trochlear

• Occulomotor
