Region where a motor neuron comes in close contact with a muscle cell.
A
neurotransmitter
B
muscular dystrophy
C
muscle tension
D
neuromuscular junction
Explanation: 

Detailed explanation-1: -The area of synaptic contact between motor neurons and their target muscle fibers is the neuromuscular junction (NMJ). This synapse occurs at a specialized area of the sarcolemma called the endplate (Figure 1).

Detailed explanation-2: -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.

Detailed explanation-3: -Towards the end of the axon terminal, closest to the muscle fiber, the tip of the axon terminal enlarges and becomes known as the synaptic end bulb. It is the synaptic end bulb of the motor neuron that comprises the nervous system component of the neuromuscular junction.

Detailed explanation-4: -The junction between a motor neuron and the sarcolemma of the muscle fibre is called the neuromuscular junction.
