A muscle cell is also known as a myocyte when referring to either a cardiac muscle cell (cardiomyocyte), or a smooth muscle cell as these are both small cells. A skeletal muscle cell is long and threadlike with many nuclei and is called a muscle fiber. Muscle cells (including myocytes and muscle fibers) develop from embryonic precursor cells called myoblasts. Web(3) The functional cells of the uterus are the myocytes, which are a homogeneous cell type responsible for the generation of contraction forces, passage of action potentials, and control of contractility. (4) The phasic contractions of the uterus are typical for visceral smooth muscle.
