The shoulder girdle (also called pectoral girdle) is a bony ring comprised of the scapula and clavicle on both sides and is closed by the sternum anteriorly. It comprises several shoulder girdle joints that connect the upper extremity with the thorax and to allow shoulder movements:

sternoclavicular joint
acromioclavicular joint
glenohumeral joint
scapulothoracic joint

The shoulder girdle is very mobile, enabling movements like protraction, retraction, elevation, depression and rotation of the scapula. All these movements are facilitated by several muscles, namely the rhomboid major and minor, the trapezius, subclavius, pectoralis minor and levator scapulae muscles.

In this video tutorial we will go over the shoulder girdle, its bones and muscles allowing the different movement in order to get an idea about the anatomy and function of this important construct.
