The muscle system that is under voluntary control is the skeletal muscle system. This type of muscle is connected to the bones and is responsible for facilitating movement through contractions that are consciously controlled by the nervous system.
Skeletal muscles work in pairs; when one muscle contracts, the opposing muscle relaxes, allowing for a range of movements such as walking, running, and lifting. Unlike smooth muscles found in internal organs, which operate involuntarily, and cardiac muscles of the heart, skeletal muscles give us the ability to perform actions at will. This is what distinguishes them in terms of control and function, making them essential for any physical activity that requires coordination and strength.
