What is the primary function of skeletal muscle?

The primary function of skeletal muscle is the movement of bones. Skeletal muscles are attached to bones and are responsible for voluntary movements, which involve contractions that pull on the bones to create movement at joints. This interaction facilitates a wide range of activities, from simple actions like walking and lifting to complex movements involved in sports and dance.

Skeletal muscles work in coordination with the skeletal system, and their ability to contract is essential for maintaining posture and enabling locomotion. While other functions, such as energy storage and some involvement in body temperature regulation, do occur, the movement of bones is the fundamental role that distinguishes skeletal muscle.
