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 ...
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]
The supraglenoid tubercle is where for the long head of the biceps brachii muscle originates. It is a small, rough projection superior to the glenoid cavity near the base of the coracoid process. The name supraglenoid tubercle refers to its location above the glenoid cavity.
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.
It is formed by the longitudinal hollow between the biceps and triceps muscles. The pulse of the brachial artery can be felt in the medial bicipital groove. [1] It should be distinguished from the bicipital groove or intertubercular sulcus, which is not a surface anatomy structure. It is the groove where the long head of biceps tendon runs ...
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.
Biceps femoris: Its long head is supplied by the tibial part of sciatic nerve, whereas the short head is supplied by the common peroneal nerve. This reflects the composite derivation from the flexor and extensor musculature.
