Â This bone is the namesake of anterior and posterior circumflex arteries that arise from the third division of the (*) axillary artery.

Â This bone is the namesake of anterior and posterior circumflex arteries that arise from the third division of the (*) axillary artery. Â Midshaft breaks of this long bone can endanger the radial nerve, which runs near this bone's deltoid tuberosity. Â Both the teres major and subscapularis muscles insert on its lesser tubercle, while the remaining rotator cuff muscles insert on its greater tubercle.
