CN functions are either...
- general (inn. more than one) or special (inn. only one)
- somatic (senses) or visceral (internal organs)
- efferent (message going out of brain to muscle), afferent (from body to brain), or mixed (both)
general somatic afferent nerves (GSA)
sensory nerves provide sensory information about the body to the brain
special somatic afferent nerves (SSA)
serve special senses of vision and hearing
general visceral afferent nerves (GVA)
info from visceral structures to brain
special visceral afferent nerves (SVA)
provide info from senses of taste smell
general visceral efferent nerves (GVE)
autonomic efferent fibers serving viscera and glands
general somatic efferent nerves (GSE)
provide innervation of skeletal muscle
special visceral efferent nerves (SVE)
involved with innervation of striates muscles of larynx, pharynx, soft palate, face and muscles of mastication (ability to chew)
