The peripheral nervous system consists of twelve pairs of cranial nerves, 31 pairs of spinal nerves, and the nerves of the autonomic nervous system. The cranial nerves are the nerves that leave the brain directly. These nerves control various actions and sensations such as sight, smell, .chewing, and swallowing, and will be the focus of this week's lab.

Of the twelve pairs of cranial nerves, two pairs arise from the forebrain, ten pairs arise from the midbrain and brain stem, and all but the Vagus nerve innervates the structures in the head and neck. Each cranial nerve pair is designated with a Roman numeral in reference to the order in which the nerves are positioned from the front to the back of the brain. The names given to the nerves indicate the structures innervated or the principle functions of the nerves.

This experiment will be conducted in pairs. Each student will test the other and record all data.
