Detailed explanation-1: -EXPLANATION: The junction between a motor neuron and the sarcolemma of the muscle fibre is called the motor end plate. It is formed at the sites, where the terminal branches of the axon of a motor neuron contact with a muscle cell.
Detailed explanation-2: -The neuromuscular junction-where nerves and muscle fibers meet-is an essential synapse for muscle contraction and movement.
Detailed explanation-3: -The space between the two is known as the synaptic cleft.
Detailed explanation-4: -What is the sarcolemma? It is the thin, transparent, extensible plasma membrane of the muscle cell. It consists of a cell membrane (plasma membrane) and an outer coat made up of a thin layer of polysaccharide (glycocalyx) material with numerous thin collagen fibrils.
