BIO 181 (Capco ASU) Exam 3 (Final Exam) Questions with Verified Solutions Briefly explain why the action potential flows only from the axon hillock to the terminal web. 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. Draw a neuron, and label all the parts as described in lecture. Draw an action potential in the axon of a neuron and indicate which ions flow int...
