where r your biceps
In human anatomy, the biceps brachii (/ËbaÉªsÉps ËbreÉªki.aÉª/), 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 forearm at the elbow and supinates the forearm.
