It is a functionally diverse nerve, offering many different modalities of innervation. The messages are converted from electrical to chemical and then back to electrical. Neurons, also known as nerve cells, send and receive signals from your brain. It is the only cranial nerve that emerges dorsally from the brain (near the back), giving it the longest pathway. Impulses are channeled along the pathway of a nerve from the central nervous system, consisting of the brain and spinal cord, to the organs of your body. Spine-Health explains that the area of skin from which a particular nerve receives sensory information is known as that nerve’s “dermatome."
