Explanation:
Detailed explanation-1: -The neuromuscular junction (NMJ) is a synaptic connection between the terminal end of a motor nerve and a muscle (skeletal/ smooth/ cardiac). It is the site for the transmission of action potential from nerve to the muscle. It is also a site for many diseases and a site of action for many pharmacological drugs.
Detailed explanation-2: -The axon terminal of a motor neuron “connects” with the muscle fiber at a place called the neuromuscular junction|], (In general, a motor neuron and the muscle fibers under its control are called a motor unit.)
Detailed explanation-3: -The junction between a motor neuron and the sarcolemma of the muscle fibre is called the neuromuscular junction.
