Final answer:
The clavicle and scapula form the shoulder girdle and meet at the acromioclavicular joint. This joint can be felt as a palpable line.
Step-by-step explanation:
The shape formed by the clavicle and scapula is known as the shoulder girdle. The clavicle, or collarbone, is a horizontal bone that meets the scapula, or shoulder blade, at the acromioclavicular joint. This joint forms a palpable line that can be felt where the clavicle meets the scapula.
