Skeletal Muscles attach to and move bones by contracting and relaxing in response to voluntary messages from the nervous system. Skeletal muscle tissue is composed of long cells called muscle fibers that have striated appearance.

Cardiac muscle tissue works to keep your heart pumping through involuntary movements. It does this through specialized cells called pacemaker cells. These control the contractions of your heart.

Smooth muscle is present throughout the body, where it serves a variety of functions. It is in the stomach and intestines, where it helps with digestion and nutrient collection. It exists throughout the urinary system, where it functions to help rid the body of toxins and works in electrolyte balance.
