axon Part of the nerve that sends the signal
dendrite part of the nerve that receives the signal
CNS Brain & Spinal cord make up the central nervous system
PNS Peripheral nerves outside the spine make up the peripheral nervous system
ANS Autonomic nervous system. Basic life functions are automatic. Nerves of the base brain and cranial nerves are included
synapse gap between nerves. The area where one nerve sends message to the next nerve.
