How muscles are involved in movement of the human fore limb?

Muscles in the human forelimb facilitate movement through contraction and relaxation, allowing for a range of motions. Skeletal muscles, attached to bones via tendons, work in pairs: when one muscle contracts, the opposing muscle relaxes, enabling actions like flexion and extension. For instance, the biceps brachii contracts to bend the elbow, while the triceps brachii extends it. Additionally, various muscle groups coordinate to enable complex movements, such as grasping or throwing.
