motor neuron and sarcolemma

Detailed explanation-1: -The junction between a motor neuron and the sarcolemma of the muscle fibre is called the neuromuscular junction.
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).
Detailed explanation-3: -The neuromuscular junction-where nerves and muscle fibers meet-is an essential synapse for muscle contraction and movement.
Detailed explanation-4: -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-5: -Motor endplates (MEPs) are important structural and functional interfaces between motor neurons and skeletal muscle fibers [1]. MEPs receive electrical signals from motor neurons, generate endplate potentials, and consequently induce muscle contractions [2].
