Brachial plexus that innervates the upper extremities.
lumbosacral plexus- L1-s5. ,
the main function of the peripheral
carries electrical impulse between the spinal cord and the periphery
what’s the role of myelin

the function of afferent
afferent is when sending the sensory impulse to the brain from the nucleus
the function of efferent is
to send the motor neurons from the stimulus .
what do axon do
that transport impulse away from the nucleus,
the function of the nodes of ranvier
is to carry the impulse
