Skeletal Muscle Fibers. Because skeletal muscle cells are long and cylindrical, they are commonly referred to as muscle fibers. Skeletal muscle fibers can be quite large for human cells, with diameters up to 100 μm and lengths up to 30 cm (11.8 in) in the Sartorius of the upper leg.During early development, embryonic myoblasts, each with its own nucleus, fuse with up to hundreds of other ...Cardiac Muscle Cells. Cardiac muscle cells, or cardiomyocytes, possess a cell membrane with specialized regions, including intercalated discs and transverse tubules. This membrane is enveloped by a lamina coat, roughly 50 nm in width. Like skeletal muscle, cardiac muscle is striated, containing myofibrils, myofilaments, and sarcomeres.Alternate route of blood to a body part through anastomosis.

Muscle tissue is subdivided into three broad categories: skeletal muscle, cardiac muscle, and smooth muscle. The three types of muscle can be distinguished by both their locations and their microscopic features.At the microscopic level, cardiac muscle is organized much like skeletal muscle. Both muscle tissues are striated, meaning they show dark and light bands when viewed under a microscope. These band are created by the highly organized sarcomeres. A sarcomere is a bundle of protein fibers which respond to a signal and contract.Cardiac Muscle. Cardiac muscle, shown in Figure 1, is found only in the heart.

Striated muscles are highly organized tissues ( Fig. 1) that convert chemical energy to physical work. The primary function of striated muscles is to generate force and contract in order to support respiration, locomotion, and posture (skeletal muscle) and to pump blood throughout the body (cardiac muscle).
