Which type of muscle is the most prevalent in the human body?

Skeletal muscle is the most prevalent type of muscle in the human body, accounting for the majority of muscle mass. This type of muscle is responsible for voluntary movements, allowing us to perform activities such as walking, lifting, and any form of physical exercise. Skeletal muscle fibers are striated, meaning they have a banded appearance under a microscope due to the organized arrangement of actin and myosin filaments.

While smooth muscle and cardiac muscle are essential for various bodily functions, they do not encompass as much mass as skeletal muscle. Smooth muscle is found in walls of hollow organs (like the intestines and blood vessels) and functions involuntarily, regulating automatic movements. Cardiac muscle is specialized tissue of the heart, working involuntarily to pump blood. Striated muscle typically refers to skeletal muscle specifically, as cardiac muscle also exhibits striations, but it is classified separately due to its unique functions and location. Thus, skeletal muscle is the predominant type that plays a major role in movement and physical activity in the human body.
