The most rapid conduction of an action potential will occur in an axon of which type?
A) Small and myelinated
B) Small and unmyelinated
C) Large and myelinated
D) Large and unmyelinated
E) Any size and myelinated

Question

Quizplus · Accepted Answer

The most rapid conduction of an action potential occurs in a large and myelinated axon because the larger diameter of the axon allows for less resistance to the flow of ions, and the myelin sheath insulates the axon, preventing the loss of electrical charge and allowing for faster conduction of the action potential.
