A Nerve Action Potential

Question

A nerve action potential
A)involves a depolarization of the neuron membrane.
B)involves movement of sodium ions from the outside to the inside of the membrane.
C)is self-propagating.
D)All of the choices are correct.
E)None of the choices is correct.

Accepted Answer

A nerve action potential involves depolarization of the neuron membrane, which causes movement of sodium ions from the outside to the inside of the membrane. The action potential is also self-propagating, meaning it moves along the length of the neuron without losing strength. Therefore, all of the choices are correct.
