The |humerus| is a long bone which forms the upper arm. Its head (proximal end) is articulated with the |scapula| (at the |glenoid cavity|), while the distal end articulates with the bones of the forearm (radius and |ulna|) to form the |elbow joint|. The |humerus| features a large, bulbous prominence on the proximal end, which is just opposite the articular head. This prominence is called the |greater tubercle|, and serves, with the lesser ~tubercle~ and points on the |scapula|, as a site of attachment for the connective tissue which forms the |shoulder joint| |capsule|.
