Document Summary
Which of the following neuroglial cells is being damaged in multiple sclerosis: astrocyte, microglial cell, oligodendrocyte. True false: gray matter consists of bundles of myelinated axons. Page 7 of 40: a stimulus either causes an action potential or it doesn"t. What does c represent: repolarization, depolarization, local potential, threshold, afterpotential, the figure illustrates the action potential. What does c represent: postsynaptic membrane, synaptic cleft, synaptic vesicle, voltage-gated calcium channel, presynaptic terminal, the figure is a process figure of the chemical synapse. Page 13 of 40: postsynaptic membrane, synaptic cleft, synaptic vesicle, voltage-gated calcium channel, presynaptic terminal. _______________________________________: the nervous system has two subdivisions - the central nervous system and the ____________ nervous system. _______________________________________: ____________ are collections of neuron cell bodies located outside of the central nervous system. _______________________________________: nerve fibers are also called ___________. _______________________________________: ____________ are processes that conduct electric signals toward the cell body.
