,cell membrane
axon
dendrite
cell body - ANS cell body
What function does a dendrite serve?
Conducts electrical impulses toward other neurons

Insulates against leakage of electrical impulses
Receives chemical messages from nearby neurons - ANS Receives chemical messages from
nearby neurons
What is the function of an axon?
Conducts outgoing electrochemical impulses toward other neurons
Receives electrical messages from neighbouring neurons
Receive chemical messages from other neurons
Provide structural support for the cell - ANS Conducts outgoing electrochemical impulses
toward other neurons

Myelinated pathway - ANS Nerve
The primary purpose of the myelin sheath is to function as what for a neuron?
Insulate the neuron so it can transmit information more efficiently
Receive messages from outside the neuron and carry them to the cell nucleus
Provide a place for neural respiration and cell metabolism to occur
Provide a soft covering to hold axons in place - ANS Insulate the neuron so it can transmit
information more efficiently
