Skeletal Muscle Anatomy and Contraction Mechanism Explained #2230384 (License: Personal Use)

The image depicts a fusiform skeletal muscle anchored by tendons to two adjacent bones, illustrating concentric contraction where muscle fibers shorten to generate force. Black arrows indicate the direction of pull on the bones, while the red muscle belly with striations highlights sarcomere alignment and the green epimysium outlines the muscle’s outer sheath. A dark tendon connects the muscle to the distal bone, emphasizing the lever action essential for voluntary movement.

Used in educational anatomy resources, medical training modules, or fitness physiology articles to explain muscle-joint mechanics; matches user intent for understanding how muscles move the skeleton during exercise or daily activity.
