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- ...
