100% Correct Answers- Latest Test | Graded
A+ | Passed
Myelination of the nerve fibers in the central nervous system is the job of the

oligodendrocyte.


T/F


✓ -:- True




If bacteria invaded the CNS tissue, microglia would migrate to the area to engulf

and destroy them. T/F


✓ -:- True




Neurons in the CNS are organized into functional groups. T/F


✓ -:- True




Efferent nerve fibers may be described as motor nerve fibers. T/F


✓ -:- True




Voltage is always measured between two points and may be called the potential

between these two points. T/F

✓ -:- True




The all-or-none phenomenon as applied to nerve conduction states that the whole

nerve cell must be stimulated for conduction to take place. T/F


✓ -:- False. The all-or-none phenomenon states that the action

potential either happens completely or it doesn't happen at all.




Enkephalins and endorphins are peptides that act like morphine. T/F


✓ -:- True




Action potentials can be generated by virtually all cells of the body because all

cells possess cell membranes. T/F


✓ -:- False. Only cells with excitable membranes, such as neurons

and muscle cells, can generate action potentials.




Acetylcholine is not a biogenic amine. T/F


✓ -:- True




In myelinated axons the voltage-gated sodium channels are concentrated at the

nodes of Ranvier. T/F

✓ -:- True




During depolarization, the inside of the neuron's membrane becomes less

negative. T or F


✓ -:- True




A graded potential that is the result of a neurotransmitter released into the

synapse between two neurons is called a postsynaptic potential. T or F


✓ -:- True




Strong stimuli cause the amplitude of action potentials generated to increase. T or

F


✓ -:- False. As stated in the all-or-none phenomenon, an action

potential occurs either completely or it doesn't happen.




A synapse formed between the axonal ending of one neuron and the cell body of

another neuron is called an axosomatic synapse. T or F


✓ -:- True




The two major classes of graded potentials are transmitter potentials and

receptor potentials. T or F

✓ -:- False. The two classes of graded potentials are generator

potentials and post-synaptic potentials




A stimulus traveling toward a synapse appears to open calcium channels at the

presynaptic end, which in turn promotes fusion of synaptic vesicles to the axonal

membrane. T or F


✓ -:- True




Sensory neurons have long dendrites, while motor neurons have long axons. T or

F


✓ -:- True




Large-diameter nerve fibers conduct impulses much faster than small-diameter

fibers. T/F


✓ -:- True




Saltatory conduction occurs because of the presence of salt (NaCl) around the

neuron. T or F


✓ -:- False. Saltatory conduction refers to the signal jumping from

node to node along the axon.
