PNS: Schwann cells wrap around axon to form the myelin sheath
CNS: Oligodendrocytes wrap their extensions around up to 60 different nerve fibers to create myelin sheaths
Resting Polarization - Interior is high with K; Exterior is high with Na
Local Depolarization - Na channels open Na increases in nerve
Activation of Nerve Impulse - Enough Na makes Na channels close and action potential occurs
Propagation of Nerve Impulse - Na increases because of nearby open Na channels and action potential propagates along length of membrane
Repolarization - K channels open and K exits the nerve
Restoration - K channels close and Na and K pumps use ATP to reset ions
Depolarization occurs when a stimulus reaches a resting neuron.
Graded Potential is a change in the membrane of a nerve cell.
This means that local depolarization can be considered graded potential.
