What is the primary function of skeletal muscles?

The primary function of skeletal muscles is to facilitate movement. Skeletal muscles are attached to bones via tendons and, when they contract, they pull on these bones, producing movement at the joints. This interaction is essential for voluntary movements, such as walking, running, and lifting objects. Additionally, skeletal muscles play a crucial role in maintaining posture and allowing precise movements required for various activities.

While other functions are contributed by skeletal muscles, they are primarily recognized for their role in enabling movement. For example, while skeletal muscles do help in stabilizing joints, that is more of a secondary role. They can also play a part in regulating blood flow through their influence on surrounding vascular systems, but the facilitation of movement remains their main purpose. Furthermore, though they can store energy in the form of glycogen, this is not their primary function compared to their direct role in allowing movement.
