neuromuscular junction. the point of junction of a nerve fiber with the muscle that it innervates. It includes an area of folded sarcolemma of the muscle fiber, and an axon terminal located in the folds and containing vesicles of the neurotransmitter acetylcholine. Called also myoneural junction.
â¢ The neuromuscular junction is the place where the terminal portion of a motor neuron axon meets a. muscle cell membrane, separated by a synaptic cleft. â¢ An action potential arriving at the axon terminal brings about the release of acetylcholine, which. leads to depolarization of the motor end plate.verview of Neuromuscular Junction Activityâ¢ The muscle cell, including the T Tubules are polarized. Stimulation of the motor end plate on amuscle cell by acetylcholine triggers depolarization resulting in contraction of the sarcomeres.Page 6.
