The muscle contraction occurs when the neural signal reaches to the target muscle fiber. The muscle fiber consists of two main components that lead to the contraction of the muscle. The two components are: Electrical component: It consists of sarcolemma, T tubule and sarcoplasmic reticulum. Mechanical component: It consists of myofibrils and myofilament.
