The biceps or biceps brachii (Latin: musculus biceps brachii, "two-headed muscle of the arm") is a large muscle that lies on the front of the upper arm between the shoulder and the elbow. Both heads of the muscle arise on the scapula and join to form a single muscle belly which is attached to the upper forearm.
The biceps brachii primarily serves to supinate the forearm at the elbow joint. [1] The muscle belly is composed of two heads. The short head is more medial and highlighted in green. The long head is more lateral and highlighted in red. A biceps tendon rupture or bicep tear is a complete or partial rupture of a tendon of the biceps brachii muscle.

The biceps femoris (/ ˈ b aɪ s ɛ p s ˈ f ɛ m ər ɪ s /) is a muscle of the thigh located to the posterior, or back. As its name implies, it consists of two heads; the long head is considered part of the hamstring muscle group, while the short head is sometimes excluded from this characterization, as it only causes knee flexion (but not hip extension) [1] and is activated by a separate ...

The anterior compartment of the arm is also known as the flexor compartment of the arm as its main action is that of flexion. The anterior compartment is one of the two anatomic compartments of the upper arm, the other being the posterior compartment. The compartment contains three muscles; the biceps brachii, the brachialis and the ...
Coracobrachialis muscle arises from the (deep surface of the) apex of the coracoid process of the scapula (a common origin with the short head of the biceps brachii [1] [2]). It additionally also arises from the proximal portion of tendon of origin of the biceps brachii muscle. [1]
It is the groove where the long head of biceps tendon runs between the greater and lesser tubercles below the humeral head before inserting into the superior glenoid rim. The lateral bicipital groove is seen on the lateral aspect of the upper arm, and is formed by the same anatomical structures as the medial groove.
