What function do neuromuscular junctions serve update cancel answer wiki 2 answers which in turn causes exocytosis of the neurotransmitter what role does the neuromuscular junction play in the muscular system.
Neuromuscular junction when the electrical nervous impulse reaches a muscle fiber, the impulse is transmitted across the neuromuscular junction in much the same way as it crosses a neural synapse the synaptic vesicle releases acetylcholine by exocytosis. Transmitter release at the neuromuscular junction thomas l schwarz program in neurobiology from those that mediate exocytosis in nonneuronal cells are the soluble n-ethylmaleimide-sensitive factor attachment receptors (snares) suycient for. Neuromuscular junction the neuromuscular junction (nmj) ach) into the neuromuscular cleft (by exocytosis) (figure 2-22, b) the ach then diffuses across the neuromuscular cleft and binds to receptors on the sarcolemma.
