Skeletal muscle is a type of muscle tissue that is responsible for moving our bones and enabling us to perform everyday activities like walking, running, and lifting. It is called "skeletal" because it is attached to the skeleton, and it is under our voluntary control, meaning we can decide when to use it. These muscles are made up of long, cylindrical fibers that can contract and relax, allowing for movement. Skeletal muscles work in pairs; when one muscle contracts, the other relaxes. For example, when you bend your arm, the biceps muscle contracts while the triceps muscle relaxes. This coordinated action helps us perform various movements smoothly and efficiently.
