An action potential moves along a(n):
|
|
dendrite
|
|
|
cell body
|
|
|
synapse
|
|
|
axon
|
|
|
myelin sheath
|
Explanation:
Detailed explanation-1: -The brief dip in the membrane potential below the normal resting voltage is termed hyperpolarization. Action potentials propagate a signal along the length of an axon differently in myelinated versus unmyelinated axons. Myelin, a lipid-rich membrane sheath surrounding some axons, insulates against the flow of ions.
