Postsynaptic receptors Study guides, Class notes & Summaries

When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. - ANSWER TRUE Briefly explain why the action potential flows only from the axon hillock to the terminal web. - ANSWER During the course of an action potential there is a refractory period that makes sure the action potential can't trigger backwards by the use of caps on gated sodium channels. The caps close and keeps the action potential flowing in one direction. How do the glial cells (i.e., m...
