Skeletal muscle is a type of muscle tissue that is attached to bones and helps the body move. It is made up of long, thin cells called muscle fibers, which can contract and relax. This contraction allows us to perform everyday activities like walking, running, and lifting objects. Skeletal muscles are under our conscious control, meaning we can decide when to use them. These muscles are also important for maintaining posture and supporting the skeleton. They work in pairs; when one muscle contracts, the other relaxes. Regular exercise, such as weightlifting or running, helps keep skeletal muscles strong and healthy, improving overall fitness.
