Muscle cells grouped together are called muscle tissue. The muscle cells contract and elongate to make the movement in the body parts. Muscle cells are found in several specialized forms such as Cardiac, skeletal or smooth muscles etc.Muscle cells grouped together are called muscle tissue.

The structures within the muscle fiber that shorten to cause skeletal muscle contraction are called myofibrils. Myofibrils are composed of repeating units called sarcomeres, which contain thick and thin filaments made of proteins (actin and myosin). When the muscle fiber is stimulated by a nerve impulse, the myosin heads interact with the actin filaments to generate the force required for muscle contraction.
Relaxation of a skeletal muscle usually involves the Golgi tendon proprioceptors.
