Description: The cranial nerves are considered components of the peripheral nervous system PNS , [1] although on a structural level the olfactory I , optic II , and trigeminal V nerves are more accurately considered part of the central nervous system CNS. Thus, damage to the nerve can produce a varied set of symptoms, depending on the site of the lesion. There are several branches of these facial nerves, each which perform a different type of function; sensory, parasympathetic or motor functions. The facial nerves of a human being have a wide array of functions, as discussed above.
