The primary component of muscle tissue is protein, with two main proteins: actin and myosin. These proteins interact to facilitate muscle contraction and movement. Muscle tissue can be categorized into three types: skeletal, smooth, and cardiac. Skeletal muscle is under voluntary control and is responsible for body movement; smooth muscle operates involuntarily in internal organs, while cardiac muscle makes up the heart. In addition to proteins, muscle tissue contains water, minerals, and a small percentage of fats, all contributing to overall muscle function and health, as well as the body’s ability to perform physical activities.
