| CN with Motor Function | supply skeletal/voluntary muscles of head
have neuronal cell bodies located in the brainstem
nuclei are within the brainstem (motor nucleus of CN VII, a discrete cluster or aggregation of motor neurons; NOT continuous with others
🗑
|
||||
| CN with Sensory Function | nerves that supply sensory info coming from the skin in and around the head
have neuronal cell bodies located in the ganglia outside the CNS (i.e. 5th CN ganglia, 7th CN ganglia)
some do have particular names, but typically it's described as a number
🗑
|
||||
| CN with Autonomic Function | some CN have autonomic function
CNs III, VII, IX, X
this autonomic function is parasympathetic because CNs only carry parasympathetic nerve fibers (i.e. the glands in and around the head -- tear glands, salivary glands, mucous glands
