Skeletal muscles are a type of muscle tissue that is attached to bones and helps the body move. They are called "skeletal" because they are connected to the skeleton. These muscles are under our control, meaning we can decide when to use them, like when we walk, run, or lift objects. These muscles are made up of long, thin cells that can contract and relax. They work in pairs; when one muscle contracts, the other relaxes. This coordinated action allows for smooth and precise movements, making activities like playing sports or dancing possible.
