Identify which compartments of the upper limb are predominantly innervated by each of the nerves of the brachial plexus below: A. Musculocutaneous nerves B. Radial nerve C. Median nerve D. Ulnar nerve    Possible choices: - posterior compartments of the arm and forearm - anterior compartment of the forearm - intrinsic hand - anterior compartment of the arm

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…

Which cranial nerve has three divisions (ophthalmic, maxillary,and mandibular)?a. accessory (CN XI)b. glossopharyngeal (CN IX)c. trigeminal (CN V)d. hypoglossal (CN XII)

Predict the symptoms (both sensory and motor) you might experience if you suffered an injury to each of the following nerves:- a. Median nerve b. Common fibular nerve c. Femoral nerve d. Sciatic nerve e. Ulnar nerve

The thalamus and hypothalamus are parts of the a. cerebrum. b. cerebellum. c. diencephalon. d. brain stem.

The thoracic spinal cord has the smallest dorsal horn area because:        a. the trunk is the most innervated area of the body and therefore there are more projections into the dorsal horn there.        b. the trunk is the least innervated area of the body and therefore there are fewer projections into the dorsal horn there.        c. most of the descending upper motor neurons have already entered the ventral horn.      d. There are many motor neurons to control the small muscles around the spine.

Name the structure indicated by the arrow in this longitudinal view of the spinal cord

The middle cerebellar peduncle directly connects the cerebellum to the  a. Midbrain b. Motor cortex c. Pons d. Spinal cord
