GENERAL HISTOLOGY

Detailed explanation-1: -Skeletal muscle fiber is referred to as a skeletal muscle cell. Inside each of these fibers are present long cylindrical structures called myofibrils . Many oval nuclei are found just beneath the plasma membrane (known as sarcolemma) of the muscle fiber. Sarcoplasm is the cytoplasm of the muscle fibre.

Detailed explanation-2: -The smallest contractile unit of skeletal muscle is the muscle fiber or myofiber, which is a long cylindrical cell that contains many nuclei, mitochondria, and sarcomeres (Figure 1) [58]. Each muscle fiber is surrounded by a thin layer of connective tissue called the endomysium.

Detailed explanation-3: -Skeletal muscles are long and cylindrical in appearance; when viewed under a microscope, skeletal muscle tissue has a striped or striated appearance. The striations are caused by the regular arrangement of contractile proteins (actin and myosin).
