Shoulder girdle bone that acts as a brace and articulates with the axial skeleton?

The bone of the shoulder girdle that acts as a brace and articulates with the axial skeleton is the clavicle, commonly known as the collarbone. It connects the sternum (breastbone) at the manubrium to the scapula (shoulder blade), providing support and stability to the shoulder. The clavicle helps to transmit forces from the upper limb to the axial skeleton, playing a crucial role in maintaining the position of the shoulder.
