E) is inhibitory.

Question

Quizplus · Accepted Answer

Myelin sheath insulates the axon and speeds up the conduction of action potentials by forcing them to jump from one node of Ranvier to the next, a process known as saltatory conduction. Therefore, conduction of action potentials in myelinated axons is faster than in unmyelinated axons.
