When an action potential develops in one location of an axon, ________.
A) it will stimulate astrocytes to release chemicals
B) it will regenerate the threshold stimulus at the originating location on the same axon
C) Schwann cells in the area begin to divide and form a solid cellular cord
D) it will propagate along the length of the axon toward the axon terminals
E) it will propagate faster along the smaller unmyelinated fibers

Question

Quizplus · Accepted Answer

When an action potential develops in one location of an axon, it will propagate along the length of the axon toward the axon terminals. This is due to the opening and closing of voltage-gated ion channels along the axon, allowing for the movement of ions and the propagation of the electrical signal.
