MUSCLE PHYSIOLOGY

Detailed explanation-1: -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-2: -There is one neuromuscular junction associated with each muscle fiber, and it is typically located near the middle of the fiber. This means that the motor end plate will also be located near the midpoint of the muscle fiber.

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

Detailed explanation-4: -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-5: -The space between the two is known as the synaptic cleft.
