The biceps muscle has two heads, the short head and the long head, distinguished according to their origin at the coracoid process and supraglenoid tubercle of the scapula, respectively. [1] From its origin on the glenoid, the long head remains tendinous as it passes through the shoulder joint and through the intertubercular groove of the ...
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 ...
Biceps tendonitis originates on the long head of the biceps brachii at the supraglenoid tubercle in 30% of cases. The main symptom is generally anterior biceps instability, but the disease can also be characterized by chronic anterior shoulder pain which radiates towards the lateral part of the elbow. [4]
The lower border of the ligament was found to be directly continuous with the tendon of origin of the long head of the biceps femoris in approximately 50% of subjects. [3] biceps femoris could therefore act to stabilise the sacroiliac joint via the sacrotuberous ligament.
A SLAP lesion (superior labrum, anterior to posterior) is a tear where the glenoid labrum meets the tendon of the long head of the biceps muscle. Symptoms include increased pain with overhead activity, popping or grinding, loss of strength, and trouble localizing a specific point of pain. [ 3 ]
A tendinous arch is frequently the origin of the long head and the tendon of latissimus dorsi. In rare cases, the long head can originate from the lateral margin of the scapula and from the capsule of the shoulder joint. [2]

The coracoid process acts as an attachment and origin for a large number of muscles (attached muscles not labeled here). The coracoid process is a thick curved process attached by a broad base to the upper part of the neck of the scapula; [2] it runs at first upward and medially; then, becoming smaller, it changes its direction, and projects forward and laterally.
