Briefly explain why the action potential flows only from the axon hillock to the terminal web.

Solution

The action potential (AP) originates from root of axon (Axon hillock) along whole axon. The peculiarity of axon hillock to initiate flow of action potential is because of the presence of higher density of voltage-gated ion channels and because of nearness to the axon. These two features ensures that the action
