Why is myelin important in the nervous system? A. It allows signals to travel faster along axons because depolarization occurs only at myelinated locations. B. It allows signals to travel faster along axons because depolarization occurs only at nonmyelinated locations. C. It bundles the dendrites of adjacent neurons together. D. It increases capacitance across the cell membrane, which helps electrical signals to leave the axons. E. It traps neurotransmitters, increasing their concentratio...

AAET Registry Exam Questions & Answers, Updated Summer 2023-2024-When the synaptic vesicles are electrically stimulated by a nerve impulse, synaptic vesicles gravitate to the outer membrane of the presynaptic wall and release acetylcholine into the synaptic cleft. The Ach molecules migrate to the postsynaptic cells where they attach to the specific receptors. When enough neurotransmitters are received by the receptors to overcome the firing threshold a CMAP is generated causing muscle contractio...
