Muscle Fibers


Large, multinucleate single cells, either cylindrical or prismatic in shape, that form the basic unit of skeletal muscle tissue. They consist of a soft contractile substance enclosed in a tubular sheath. They are derived from the fusion of skeletal myoblasts (MYOBLASTS, SKELETAL) into a syncytium, followed by differentiation.
