1. An action potential is best described as which of the following statements::
-
large, depolarizing signal that is actively propagated along an axon by
repeated generation of a signal
2. A ____ plane divides a structure into anterior and posterior portions: coronal
3. The functions of myelin (white matter) on axons are which of the following?-
: provides insulation which aids in transmission of electrical potentials
4. The neurotransmitter Glutamate aligns with what category and has what
type of action on the postsynaptic membrane during an action potential:
amino acid, excitatory
5. The central nervous system is made up of what structures?: cerebrum,
brainstem and cerebellum, and the spinal cord
,6. True or False: an increase in the strength or duration of an excitatory
stimulus to the presynaptic cell results in increased or prolonged Ca2+ entry
into the presynaptic terminal, ultimately leading to further neurotransmitter
release from the presynaptic terminal: True
7. The pathology of Multiple Sclerosis is best described as which of the fol-
lowing:: immune system produces antibodies that primarily attack
oligodendrocytes causing patches (plaques) of destruction of the myelin
(demyelination)
