The unusual microscopic anatomy of a muscle cell gave rise to its terminology. The cytoplasm in a muscle cell is termed the sarcoplasm; the smooth endoplasmic reticulum of a muscle cell is termed the sarcoplasmic reticulum; and the cell membrane in a muscle cell is termed the sarcolemma. The sarcolemma receives and conducts stimuli.

Webb23 juli 2024 · The smooth myocytes are muscle cells that are non-striated. They are elongated and spindle-shaped. The cardiac myocytes are muscle cells that contain one or sometimes two nuclei and myofibrils, and are separated from one another by an intercalated disk. WebbMuscle tissue is a soft tissue that is primarily composed of long muscle fibers. The coordinated interaction of the myofilaments actin and myosin within the myocytes gives muscle tissue the ability to contract.
