Articulación esternoclavicular – Wikipedia, a enciclopedia libre
The parts entering into its formation esternoclavlcular the sternal end of the clavicle, the upper and lateral part of the manubrium sterni, and the cartilage of the first rib. Usted puede, a riesgo de afectar la calidad de su experiencia de usuario, cambiar edternoclavicular siguientes configuraciones: The shoulder is drawn backward by the Rhomboidei and the middle and lower fibers of the Trapezius, and forward by the Serratus anterior and Pectoralis minor.
The depression of the shoulder is principally effected by gravity assisted by the Subclavius, Pectoralis minor and lower fibers of the Trapezius.
The ligaments of this joint are: Articular capsule Articular disc Anterior sternoclavicular ligament Posterior sternoclavicular ligament Costoclavicular ligament Interclavicular ligament The Articular Capsule capsula articularis; capsular ligament.
The ligaments of this joint are:.
This definition incorporates text from a public domain edition of Gray’s Anatomy 20th U. This joint therefore forms the center from which all movements of the supporting arch of the shoulder originate, and is the only point of articulation of the shoulder girdle with the trunk.

When these movements take place in the joint, the clavicle in its motion carries the scapula with it, this bone gliding on the outer surface of the chest.
In front and behind it is of considerable thickness, and forms the anterior and posterior sternoclavicular ligaments; but above, and especially below, it is thin and partakes more of the character of areolar than of true fibrous tissue. The Articular Capsule capsula articularis; capsular ligament. The articular surface of the clavicle is much larger than that of the sternum, and is invested with a layer of cartilage, which is considerably thicker than that on the latter bone.
The movements attendant on elevation and depression of the shoulder take place between the clavicle and the articular disk, the bone rotating upon the ligament on an axis drawn from before backward through its own articular facet; when the shoulder is moved forward and backward, the clavicle, with the articular disk rolls to and fro on the articular surface of the sternum, revolving, with a sliding movement, around an axis drawn nearly vertically through the sternum; in the circumduction of the shoulder, which is compounded of these two movements, the clavicle revolves upon the articular disk and the latter, with the clavicle, rolls upon the sternum.
The sternoclavicular articulation is a double arthrodial joint.
Elevation of the shoulder is limited principally by the costoclavicular ligament; depression, by the interclavicular ligament and articular disk.
