What is a primary function of the muscular system?

The primary function of the muscular system is the movement and stabilization of joints. Muscles work in coordination with the skeletal system to facilitate movement throughout the body, allowing for various activities such as walking, running, lifting, and grasping. When muscles contract, they pull on bones to create movement, while also supporting posture and maintaining balance. This function is essential for overall mobility and physical activity.

In addition to movement, the stabilization of joints is crucial. Muscles surrounding joints provide support and keep joints stable during movement, preventing injuries and allowing for more effective movement patterns. This dual role of enabling movement while providing stability is fundamental to the muscular system's contributions to overall body function.
