Orthodromic response - Study guides, Class notes & Summaries

AAET registry exam questions with correct answers 2023 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...
