Verified step by step guidance1
Understand the anatomy of the pectoral girdle, which is part of the appendicular skeleton and connects the upper limb to the trunk.
Identify the bones that make up the pectoral girdle. The pectoral girdle consists of two main bones: the clavicle and the scapula.
Recognize that the humerus, femur, and tibia are not part of the pectoral girdle. The humerus is the bone of the upper arm, while the femur and tibia are bones of the lower limb.
Focus on the clavicle, which is a long bone that serves as a strut between the shoulder blade and the sternum, providing support and stability to the shoulder.
Conclude that the clavicle is indeed part of the pectoral girdle, as it is one of the two bones that form this structure.
