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
Ans: 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?
Ans: They are chemically broken down by enzymes and recycled back to
