Ion channels are located _________ of myelinated axons.
A) along the entire length

D) only at the axon hillock

Question

Quizplus · Accepted Answer

Ion channels are primarily located at the nodes of Ranvier and the axon hillock in myelinated axons. The myelin sheath insulates the axon and prevents the flow of ions, causing the action potential to "jump" from node to node for faster conduction. The ion channels facilitate the movement of ions across the axonal membrane at these points.
