Which two bones make up the shoulder girdle?

1. Clavicle and Humerus

2. Humerus and Scapula

3. Clavicle and Scapula

4. Scapula and Radius

The correct answer is: Clavicle and Scapula

The shoulder girdle, also known as the pectoral girdle, consists of two primary bones: the clavicle and the scapula. The clavicle, commonly referred to as the collarbone, connects the arm to the body and acts as a structural support that transfers weight from the upper limb to the axial skeleton. The scapula, or shoulder blade, provides attachment points for muscles and plays a crucial role in facilitating shoulder movement and stability. Understanding the functions and relationships of these bones is important for grasping biomechanics and movement in sports science. The other options include bones that do not contribute to the composition of the shoulder girdle. The humerus is the bone of the upper arm, while the radius is one of the forearm bones, hence they cannot be included in the shoulder girdle.
