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...

True (T/F) Excitatory synapses cause depolarization of the post-synaptic cell. True (T/F) Excitatory synapses cause hyperpolarization of post-synaptic cells. False (T/F) Excitatory synapses make the post-synaptic ce...
