| Costal Cartilage | Attach ribs to sternum |
| Pectoral Girdle | Set of bones in the appendicular skeleton |
| Clavicle | "Collarbone"; is "S" shape |
| Scapula | "Shoulder blade" |
| Acromion | Forms the tip of the shoulder; articulates with the clavicle |
| Coracoid Process | Curves anteriorly and inferiorly to the acromion process |
