Skeletal muscle is a type of muscle tissue that is attached to bones and helps the body move. It is called "skeletal" because it is connected to the skeleton. These muscles are under voluntary control, meaning we can decide when to use them, like when we walk, run, or lift objects. They are made up of long, thin cells 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 coordination is essential for smooth and controlled movements in everyday activities.
