Excitatory synapses make the post-synaptic cell less likely to fire. - ANSWER-False The neural tissues are: - ANSWER-Spinal cord, sensory neurons, and brain How do the glial cells (i.e., myelin sheath) speed up the firing of neurons? - ANSWER-The cell wraps extensions of a fatty insulating substance (myelin) around the axons of neurons. The action potential is: - ANSWER-A result of the movement of ions. Receptors are made from membrane-bound polyribosomes. - ANSWER-True List the 4...

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- ...
