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 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.
Most agree that the proximal tendon of the long head of the biceps brachii muscle becomes fibrocartilaginous prior to attaching to the superior aspect of the glenoid. The long head of the triceps brachii inserts inferiorly, similarly. [6] Together, all of those cartilaginous extensions are termed the 'glenoid labrum'. [citation needed]
It identifies the presence of a pathology involving the biceps tendon or glenoid labrum. The specific positive findings to the test include pain in the bicipital groove indicating biceps tendinitis, [2] [3] subluxation of the long head of the biceps brachii muscle, [3] and presence of a SLAP tear.

The bicipital aponeurosis originates from the distal insertion of the biceps brachii, and inserts into the deep fascia of the forearm. [1] The biceps tendon inserts on the radial tuberosity, and the bicipital aponeurosis lies medially to it. [2] It reinforces the cubital fossa, helping to protect the brachial artery and the median nerve running ...
Beneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity; its surface is divided into: . a posterior, rough portion, for the insertion of the tendon of the biceps brachii.
The supraglenoid tubercle is a region of the scapula from which the long head of the biceps brachii muscle originates. [1] [2] It is a small, rough projection superior to the glenoid cavity near the base of the coracoid process. The term supraglenoid is from the Latin supra, meaning above, and glenoid, meaning socket or cavity. [3]
