Cardiac and skeletal muscle both possess striations..

Skeletal muscles are located throughout the body at the openings of internal tracts to control the movement of various substances. These muscles allow functions, such as swallowing, urination, and defecation, to be under voluntary control. Skeletal muscles also protect internal organs (particularly abdominal and pelvic organs) by acting as an ... 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. The cardiac muscle cells, or cardiomyocytes, possess an endomysium and perimysium but do not have an epimysium. Compared to skeletal muscles, cardiac muscle cells are small and mostly have a single nucleus. Additionally, they are usually branched and composed of regularly arranged sarcomeres in the myofibrils, giving them a striated appearance.Organization of the Sarcomere Organizational details of a typical striated skeletal muscle. a: Representation of each muscle fiber showing the parallel bundles call myofibrils.b: Myofibrils are a series of sarcomeres separated by Z discs (also called Z bands) which contain thick and thin filaments.c: Thick filaments are myosin bundles that span the A line and are bound to proteins of the M ...

Skeletal muscle is an excitable, contractile tissue responsible for maintaining posture and moving the orbits, together with the appendicular and axial skeletons. It attaches to bones and the orbits through tendons. Excitable tissue responds to stimuli through electrical signals. Contractile tissue is able to generate tension of force.Cardiac muscle is a type of tissue that develops from the mesoderm during embryonic development. It develops from the cells of the primitive heart tube, aligns into chain like arrays, and has the same arrangement of its contractile filaments as seen in skeletal muscle.
