Similar to skeletal muscle, cardiac muscle is striated and organized into sarcomeres, possessing the same banding organization as skeletal muscle (Figure 9.6.1 9.6. 1 ).Both cardiac and skeletal muscle tissues are striated and smooth muscle is not, hence its name. Skeletal muscle cells have more than one nucleus, are large and run parallel to each other. Cardiac muscle cells usually have only one, sometimes two, centrally located nuclei and are branched. They also are connected to each other via gap junctions.

In 1510, Leonardo Da Vinci was the first to describe the heart muscle as arranged in longitudinal and transverse fibers and their contraction resulted in shortening and widening of the ventricular cavities. 1 Since then, there has been a divergence in the study of cardiac and skeletal muscle cells because of the complexity in structure and function of cardiac myocytes.

Function of Cardiac Muscle. As in skeletal muscle, the signal to contract is an action potential. However with skeletal muscle this signal usually comes from the somatic, or voluntary, nervous system. Cardiac muscle is controlled by the autonomous nervous system. Cells …Although both cardiac and skeletal muscles are striated, skeletal muscle is composed of slow (type I) and fast (type II) fibers, whereas cardiac muscle consists of a single fiber type, most similar to type I skeletal muscle fibers. In contrast, smooth muscle cells are not striated but rather consist of dense bodies and intermediate filaments. To determine the difference between the two types of striated muscle tissue, look for long, multinucleated cells that are arranged parallel to one another in skeletal muscle tissue. By contrast, cardiac muscle cells are shorter and wider, branched, and generally have only one or two nuclei. Intercalated discs are unique to cardiac muscle cells.
