Write the name of each cranial nerve next to the Roman numeral representative of that nerve. Then draw a line to link each nerve to its characteristics. Some characteristics may link to VII. more than one nerve, while other nerves may have more than one characteristic. a. Mixed branch controls chewing and detects sensations in lower jaw b. Links the retina to the brain's visual cortex; III damage causes blindness in part or all of a visual field IV c. Regulates voluntary movements of the eyelid and eyeball V VI d. Damage to sensory branch causes loss of sensation in upper face VII VIII e. Governs tongue movements, swallowing, and gagging IX f. Damage causes tongue to deviate toward injured side X XI g. Damage here can cause a drooping eyelid and dilated pupil XII h. Damage causes sagging facial muscles and distorted sense of taste i. Longest and most widely distributed cranial nerve j. Concerned with hearing and balance k. Plays a key role in many heart, lung, digestive, and urinary…
