WVU Biology 102 Exam 5 Questions and Answers Already Passed What are the functional units of the nervous system? neurons Basic structure / function of the neuron - dendrites, cell body and axon. Dendrites- receive impulses from the synapses of other Axon- place along which the message is sent. Long rope like object. Myelin Sheath- cover around the Axon, increases the speed of the message sent. What happens during an "action potential"? Sodium (Na) start out and then rushes in- ...

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...
