Which cranial nerve innervates most of the visceral organs?

Vagus Let's look at the list of cranial nerves to see what they do 0. Terminal - Animal tests indicate this nerve is involved in detecting pheromones. I. Olfactory - Handles the sense of smell. II. Optic - Handles the transmission of visual signals. III. Oculomotor - Handles the movement of your eyes. IV. Trochlear - More eye movement. V. Trigeminal - Allows you to sense touch on your face and chew your food. VI. Abducens - More involvement with the eyes. VII. Facial - The name says it all. VIII. Vestibulocochlear - Sense of hearing and balance using the inner ear. IX. Glossopharyngeal - Taste and some motor movement. X. Vagus - This one innervates nearly all of the thoracic and abdominal viscera. And that pretty much defines the question. So this is the nerve to choose. XI. Accessory - Handles a few muscles. XII. Hypoglossal - Handles a long of the tongue movement.
