2023年7月24日 · Shoulder and Upper limb muscles are specialized to perform functions of pressure and manipulation of objects. Skeletal muscle is formed by myofibers which contain millions of myofibrils, and each of them is formed by sarcomeres. Sarcomeres are the contractile unit, therefore skeletal muscle fibers are completely dedicated to generating force.

It consists of 30 bones, including the clavicle, scapula, humerus, radius, ulna, and the bones of the hand. This article provides an in-depth exploration of the anatomy, development, functions, and clinical significance of the bones of the upper limb.

Most commonly dislocated major joint in body. Stability depends almost entirely on the strength of surrounding muscles (Rotator Cuff). Commonly dislocated anteriorly and inferiorly. Anteriorly shoulder joint protected by subscapularis. Superiorly shoulder joint protected by supraspinatus.
