Answer» your answer Neuromuscular junction is a point of contact between the end plate of AXON of a motor NEURON with surface membrane (sarcolemma) of a muscle cell. The knob at the end of terminal branches of motor axon is SEPARATED from the sarcolemma by a NARROW space, the synaptic cleft. The neurotransmitter released from the vesicles of knob of excited motor neuron is acetylcholine which passes through postsynaptic muscle membrane and excitation SPREADS over the whole muscle fibre making it to contract.HOPE IT IS USEFUL |
