BIO 181 ASU EXAM 3 Short Answers Briefly explain why the action potential flows only from the axon hillock to the terminal web. - CORRECT ANSWER-The action potential originates from the axon hillock which initiates the flow of the action potential because of the presence of higher density voltage-gated ion channels. List the 4 types of glial cells and list a phrase to describe their function. - CORRECT ANSWER-- Microglia: cleans up cellular debris - Astrocytes: support and repair neurons ...
