MEDICAL PHYSIOLOGY

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: -From here, the action potential is sent through an axon down to its ending branches, called axon terminals, to muscle fibers which they innervate. The place where an axon terminal meets the muscle fiber is the neuromuscular junction.

Detailed explanation-3: -The neuromuscular junction-where nerves and muscle fibers meet-is an essential synapse for muscle contraction and movement.

Detailed explanation-4: -The space between the two is known as the synaptic cleft.
