What is the primary function of skeletal muscle?

The primary function of skeletal muscle is to facilitate movement by contracting and pulling on bones. Skeletal muscles are attached to bones via tendons and, when they contract, they exert force on the bones, enabling the body to move. This movement allows for a wide range of activities, including walking, running, lifting, and other physical tasks. The contraction of skeletal muscles is under voluntary control, meaning that individuals can consciously decide to initiate or stop movement. This ability to control muscle contraction is essential for coordination and physical activity.

The other options focus on functions that are not directly related to the role of skeletal muscle, which is specifically designed for locomotion and movement. For instance, while some muscles may play roles in protection or energy storage, those functions are not the primary role of skeletal muscle.
