What is the proximal end of the humerus called?

The proximal end of the humerus is referred to as the head of the humerus. This part of the bone is rounded and articulates with the glenoid cavity of the scapula, forming the shoulder joint. The head plays a crucial role in mobility and stability within the shoulder girdle, allowing for a wide range of movements.

The neck of the humerus, found just below the head, is a narrower region that connects the head to the shaft. The trochlea and capitulum are located at the distal end of the humerus and are involved in articulating with the forearm bones, specifically the ulna and radius. The distinct features of the proximal end of the humerus are what set the head apart from these other parts, making it the defining term for that section of the bone.
