AAET REGISTRY EXAM QUESTIONS AND ANSWERS
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 contraction. This describes - Answers :The events that occur in the
Neuromuscular Junction
What happens to the neurotransmitters after they have attached themselves to
receptors and generated the muscles to contract? - Answers :They are chemically
broken down by enzymes and recycled back to the presynaptic terminals
Maximal stimulation is appropriate for _______, while supramaximal stimulation (not
over stimulation) is necessary in ________recordings. - Answers :SNC, MNC
