What structures make up the shoulder girdle?

1. Vertebrae and ribs

2. Collarbone and shoulder blades

3. Hips and knees

4. Skull and jawbone

The correct answer is: Collarbone and shoulder blades

The shoulder girdle is primarily composed of the collarbone, also known as the clavicle, and the shoulder blades, referred to as the scapulae. These structures work together to provide support and mobility to the shoulder joint, allowing for a wide range of motion in the arms. The clavicle plays a crucial role in connecting the upper limb to the body, while the scapula serves as the attachment point for various muscles that facilitate movement. Together, these structures allow for the complex movements required in activities such as throwing, lifting, and reaching. Other options, such as vertebrae and ribs, relate to the spinal and thoracic structure but do not encompass the shoulder girdle. Similarly, hips and knees refer to structures of the lower body, while the skull and jawbone pertain to cranial and facial anatomy, respectively, which are unrelated to the shoulder girdle.
