Where is the Central Nervous System located?
Brain & Spinal Chord
Where is the Peripheral Nervous System located?
In the nerves
Myelinated is…
A sheath, insolation on an axon & moves fast
Un myelinated is…
Unsheathed, uninsulated axon & moves slow
What is the Enteric Nervous System?
Gut to brain communication
