The biceps brachii is a muscle in the anterior compartment of the arm. It has two heads, the long head and the short head. It is one of three muscles in the anterior compartment of the arm, the other two muscles being the brachialis and the coracobrachialis, which lie deep to it.
The biceps muscle receives innervation via the musculocutaneous nerve and it functions mainly to supinate the forearm and flex the elbow.
Despite being a relatively small muscle, the biceps brachii is one of the most highly trained muscles in the gym, along with the pectoral muscles and the deltoid muscles.
If you are a fitness enthusiast, what exercises do you use to train this muscle?
|Biceps Brachii||- Flexion of elbow|
- Supination of forearm
