The bones of the shoulder girdle (cingulum membri superioris) include the clavicle (clavicula) and the scapula (scapula).

The clavicle is a paired tubular bone located between the clavicular notch of the sternum and the acromion.

The clavicle has two surfaces:

• Superior facet (facies superior)

• Inferior facet (facies inferior)

  

  There are also three main parts:

• Body of the clavicle (corpus claviculae)

  

• Sternal end (extremitas sternalis)

  

• Acromial end (extremitas acromialis)

  

  At the sternal end lies the sternal facet (facies articularis sternalis), which connects to the sternum (namely, the clavicular notch).

  And at the acromial end we can distinguish the acromial facet (facies articularis acromialis), which forms a joint with the acromion.

  

  

  On the inferior surface of the clavicle, there are several formations:

• At the sternal end, there is the impression for the costoclavicular ligament (impressio ligamenti costoclavicularis)

  

• At the acromial end there is the tuberosity for the coracoclavicular ligament (tuberositas ligamenti coracoclavicularis), which is divided into two component: the conoid tubercle (tuberculum conoideum), to which the conoid ligament is attached, and the trapezoid line (linea trapezoidea), to which the trapezoid ligament is attached

  These ligaments form the coracoclavicular ligament, which is present between the clavicle and the coracoid process of the scapula.

  

  

  

• Furthermore, there is the subclavian groove (sulcus musculi subclavii) on the inferior surface of the body
