In human anatomy the biceps brachii (/ˈbaɪsɛps ˈbræki.aɪ/) commonly known as the biceps is a two-headed muscle that lies on the upper arm between the shoulder and the elbow. Both heads arise on the scapula and join to form a single muscle belly which is attached to the upper forearm. While the biceps crosses both the shoulder and elbow joints its main function is at the latter where it flexes the elbow and supinates the forearm.
