Thebicipital groove (intertubercular groove,sulcus intertubercularis) is a deep groove on thehumerus that separates thegreater tubercle from thelesser tubercle. It allows for the long tendon of the biceps brachii muscle to pass.
The bicipital groove separates thegreater tubercle from thelesser tubercle.[1] It is usually around 8cm long and 1 cm wide inadults.[1] The groove lodges the long tendon of thebiceps brachii muscle, positioned between the tendon of thepectoralis major muscle on the lateral lip and the tendon of theteres major muscle on the medial lip. It also transmits a branch of theanterior humeral circumflex artery to theshoulder joint.[citation needed]
The insertion of thelatissimus dorsi muscle is found along the floor of the bicipital groove. Theteres major muscle inserts on the medial lip of the groove.[citation needed]
It runs obliquely downward, and ends near the junction of the upper with the middle third of the bone. It is the lateral wall of theaxilla.[2]
The bicipital groove allows for the long tendon of the biceps brachii muscle to pass.[1]
