GROSS ANATOMY

Detailed explanation-1: -The greater tubercle of the humerus is a bony projection of the lateral part of the proximal end of the humerus. It is situated lateral to the head of the humerus, and posterolateral to the lesser tubercle of humerus.

Detailed explanation-2: -Greater Tubercle-a bony prominence located on the lateral side of the proximal humerus; serves as an attachment site for muscles that act across the shoulder joint.

Detailed explanation-3: -The greater tubercle is the most lateral portion of the proximal end of the humerus. It consists of three smooth and flat impressions at the posterosuperior aspect for the attachment of muscles.

Detailed explanation-4: -The greater tubercle is located on the craniolateral part of the proximal extremity of the humerus, separated from the head by the neck of humerus. It gives insertion for the muscles of the shoulder blade (infraspinous and supraspinous muscles).

Detailed explanation-5: -The lateral surface of the greater tubercle is convex, rough, and continuous with the lateral surface of the body of the humerus. It can be described as having a cranial and a caudal part. Between the greater tubercle and the lesser tubercle is the bicipital groove (intertubercular sulcus).
