Types include proximal humeral fractures, humeral shaft fractures, and distal humeral fractures. It also helps stabilise the humeral head in the glenoid cavity. The axillary nerve and the posterior humeral circumflex artery pass through the space. The plastron features paired gular, humeral, pectoral, abdominal, femoral, and anal scutes. The glenoid appears to be oriented dorsolaterally permitting a wide range of humeral movement. It makes contact with the axillary nerve and the posterior humeral circumflex artery. The cuff adheres to the glenohumeral capsule and attaches to the humeral head. The internal tuberosity of the humeral proximal end is short. It also transmits a branch of the anterior humeral circumflex artery to the shoulder joint. The change of the femoral feathers begins later than that of the humeral ones. Kanyon injured his left shoulder, suffering a humeral head contusion and supraspinatus tendinitis. The most common injury is the humeral shaft fracture. The examiner's proximal hand is to be placed over the patient's humeral head. In burrowing moles, the clavicle and the humeral head are connected. The greater tubercle projects as the most lateral structure of the humeral head.
