The primary function of skeletal muscle in animals is to facilitate movement. Skeletal muscles are attached to bones and are under voluntary control, allowing for precise movements essential for activities like walking, running, and manipulating objects. These muscles contract in response to signals from the nervous system, enabling dynamic postures and force generation. Additionally, skeletal muscles play a role in maintaining posture and supporting body structure. Their adaptability to training and physical demands is crucial for overall mobility and physical performance in various species.
