Neurons that conduct impulses from the CNS to muscles or glands are - CORRECT ANS motor neurons. Which cells produce myelin in the brain and spinal cord? - CORRECT ANS Oligodendrocytes Every neuron has - CORRECT ANS a cell body. If a resting potential becomes more negative, the membrane is - CORRECT ANS hyperpolarized. Which of the following neuroglia are not part of the CNS? - CORRECT ANS Satellite cells Three general functions of the nervous system are - CORRECT ANS integrative, motor, and sensory. The brain and spinal cord comprise the central nervous system. - CORRECT ANS True The most rapid conduction of an impulse along an axon occurs on a fiber that is - CORRECT ANS thick and myelinated. During the absolute refractory period, a stimulus of high intensity may trigger a nerve impulse. - CORRECT ANS False The neurotransmitter that controls skeletal muscle contraction is - CORRECT ANS acetylcholine. Because the response of a nerve fiber is all-or-none, a greater intensity of stimulus does not produce a stronger impulse. - CORRECT ANS True
