Accessed 20 July 2020 === Acromioclavicular Joint (Articulatio acromioclavicularis) === This is articulation between the acromial end of the clavicle and the acromion of the scapula. It enables slight gliding movement about the shoulder region. It is a synovial joint surrounded by a capsule of articular cartilage filled with intra-articular synovium. === Sternoclavicular Joint (Articulatio sternoclavicularis) === This is the articulation between the sternal end of the clavicle and the manubrium of the sternum. This synovial joint is important as it attaches the clavicle and scapula to the axial skeleton. The joint enables a variety of limited movements of the arm, including: * Protraction and retraction * Elevation and depression * Axial rotation === Muscle attachments === A total of five muscles are attached to the clavicle, found distributed at either the lateral third or medial two thirds of the bone. Two muscles are attached to the lateral third of the clavicle: * The [[trapezius]] muscle, which is attached along the posterior surface of the lateral third of the clavicle. * The [[deltoid]] muscle, where the anterior portion of the muscle is attached to the periosteum at the anterior surface of the bone. Three muscles are attached to the medial third of the clavicle: * The [[sternocleidomastoid]] muscle, clavicular head of the muscle attaches to the medial third of the clavicle. * The [[pectoralis major]] muscle, which is attached to the anterior surface of the bone. * The subclavius muscle, which is attached to a groove found in the middle of the bone’s inferior surface. From there, the muscle extends into both lateral and medial areas of the clavicle.Kenhub. Clavicle.
