Understand the anatomy of the shoulder girdle: The shoulder girdle, also known as the pectoral girdle, is the set of bones that connects the upper limb to the axial skeleton and provides support and mobility.
Identify the bones involved: The shoulder girdle consists of two main bones—the clavicle (collarbone) and the scapula (shoulder blade). These bones work together to form the structure of the shoulder girdle.
Clarify the role of the clavicle: The clavicle is a long, slender bone that runs horizontally between the sternum (breastbone) and the scapula. It helps stabilize the shoulder and provides attachment points for muscles.
Clarify the role of the scapula: The scapula is a flat, triangular bone located on the posterior side of the rib cage. It serves as an attachment site for muscles and articulates with the humerus to form the shoulder joint.
Eliminate incorrect options: The sternum is part of the axial skeleton, not the shoulder girdle. The humerus and radius are bones of the arm, not the girdle. Therefore, the correct answer is the clavicle and scapula.
