30 Οκτ 2023 · The humerus is the longest and largest bone of the upper limb. It consists of a proximal end, a shaft and a distal end, all which contain important anatomical landmarks. The humerus articulates with the scapula proximally at the glenohumeral joint so it participates in the movements of the shoulder.
As a consequence the shoulder joint is highly mobile, where stability takes second place to mobility, as is evident from the shape of the osseous structures: a large humeral head lying on an almost flat scapular surface. Stability is provided mainly by ligaments, tendons and muscles; the bones and capsule are of secondary importance.

7 Αυγ 2023 · The humerus is the largest bone of the upper extremity and defines the human brachium (arm). It articulates proximally with the glenoid via the glenohumeral (GH) joint and distally with the radius and ulna at the elbow joint.
The supraspinatus muscle is an abductor, a capsule tensor and a guiding muscle in the shoulder joint. When abducting the arm, the deltoid muscle pulls the greater tuberosity under the fornix of the humerus. Rotation of the humerus displaces the supraspinatus tendon.
8 Αυγ 2023 · Muscles. The primary muscle group that supports the shoulder joint is the rotator cuff muscles. The four rotator cuff muscles are the supraspinatus, infraspinatus, teres minor, and subscapularis. Together the rotator cuff muscles form a musculotendinous cuff as they insert on the proximal humerus.
The tendon of biceps brachii muscle is also part of the capsule, the capsule covers the intertubercular groove, and forms an intertubercular synovial vagina around the tendon • Insertion: anatomical neck of humerus
