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...

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...

Bio 181 ASU Exam 3 Questions with complete solutions List the 4 types of glial cells and list a phrase to describe their function. - answer1. Schwann cells wrap around the axon of a cell in the PNS, while providing electrical insulation. 2. Oligodendrocytes do the same thing as Schwann cells but they do it in the CNS. 3. Astrocytes protect the brain from toxic chemicals. 4. Microgilia protect the brain. T/F When the presynaptic cells contacts a muscle cell, the synapse area is called a mo...
