Plasma membrane of the muscle cell. The contractile unit in a skeletal muscle cell is called the sarcomere.
Sarcomere An Overview Sciencedirect Topics
One myofibril is divided into segments called sarcomeres.
. What is the contractile unit of the muscle fiber called. Each sarcomere is composed of two main protein filamentsactin and myosinwhich are the active structures responsible for muscular contraction. Sarcomeres are organized in series to make up a myofibrilWhat is a contractile unitA sarcomere is the functional unit contractile unit of a muscle fiber.
Every sarcomere is basically made from the actin and myosin proteins. Thin connective tissue investing each muscle cells. Depicted in Figure 1 is the sarcomere which is the basic contractile unit of striated muscle.
