Corpus: Transverse humeral ligament

The intertubercular sulcus of the humerus is transformed into an osteofibrous canal by the transverse humeral ligament. The long head of the biceps tendon runs within this canal, thus being fixed in place by the transverse humeral ligament in the intertubercular sulcus of the humerus.

According to some authors, the transverse humeral ligament is not a ligament in the strict sense. Rather, it is believed to be fiber extensions of the subscapular muscle or the joint capsule, attaching to the lesser tubercle.
