MICROANATOMY

Detailed explanation-1: -Between the synaptic end bulbs of the neuron and the cell membrane of the muscle fiber (the sarcolemma) lies a space known as the synaptic cleft, which is the final component of the neuromuscular junction.

Detailed explanation-2: -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-3: -sarcolemma (= plasma membrane) in the junctional grooves is highly folded and is often called the motor end plate (= sole plate). Many authorities, however, prefer to use the term motor end plate to refer to the terminal branches or entire neuromuscular junction.

Detailed explanation-4: -The neuromuscular junction-where nerves and muscle fibers meet-is an essential synapse for muscle contraction and movement.

Detailed explanation-5: -The space between the two is known as the synaptic cleft.
