Cranial Nerves Numeral
Terms in this set (16)
(12)-->are found on the underside of the brain originating from the brain stem and pass through the Magnum Foramen in the skull to the head, neck, and trunk. They are concerned mostly with carrying sensory input from the skin and sense organs of the Head and Neck and transporting/transmitting motor output to the muscles of these regions. Some cranial nerves are purely sensory, others are mixed. Cranial nerves are numbered using Roman Numerals and are typically named according to their primary function.
Cranial Nerve Functions
Keep in mind that the cranial nerves are characterized not only by name, but by a number which is designated by a Roman Numeral. Here is a list of the Cranial Nerves as well as the SIMPLEST function/or what each one is responsible for controlling.
