    The rib cage is a bony and cartilaginous structure. A typical rib cage consists of 24 ribs (12 pairs), the sternum (an inverted T-shaped structure connecting the rib bones), costal cartilages and the 12 thoracic vertebrae shown in the diagram below. The first seven pairs of ribs connect directly to the sternum and are referred to as true ribs. The remaining five pairs of ribs do not connect directly to the sternum and are referred to as false ribs. The rib cage aids in the protection of the heart and lungs.
