Best Answer: A muscles contraction (also known as a muscle twitch or simply twitch) occurs when a muscle fibre generates tension through the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten or remain the same. Though the term 'contraction' implies a shortening or reduction, when used as a scientific term referring to the muscular system contraction refers to the generation of tension by muscle fibers with the help of motor neurons. Contraction is will happen once a muscle is stimulated by a threshold stimulus. Muscle Contraction. 1. The distal end of a motor neuron releases acetylcholine. 2. Acetylcholine diffuses across the gap at the neuromuscular junction. 3.
