Verified step by step guidance

Step 1: Understand the thoracic cage's anatomy. The thoracic cage is a bony structure that protects vital organs such as the heart and lungs. It consists of the sternum, ribs, and thoracic vertebrae.

Step 2: Review the components of the thoracic cage. The sternum is the flat bone at the front of the chest, the ribs are curved bones that form the sides of the cage, and the thoracic vertebrae are the spinal bones that connect to the ribs at the back.

Step 3: Examine the clavicle's location and function. The clavicle, or collarbone, is a long bone that connects the shoulder to the sternum but is not part of the thoracic cage. It is part of the pectoral girdle, which supports the upper limbs.

Step 4: Compare the clavicle to the other options. The sternum, ribs, and thoracic vertebrae are all directly involved in forming the thoracic cage, while the clavicle is anatomically separate.

Step 5: Conclude that the clavicle is NOT part of the thoracic cage based on its anatomical location and function.
