Question

Quizplus · Accepted Answer

The 12 thoracic vertebrae articulate with all 12 ribs, but not all ribs connect directly with the sternum anteriorly. The first 7 ribs connect directly with the sternum via cartilages and are called vertebrosternal ribs. Ribs 8 to 10 are connected to the lower sternum by a common cartilage and are called vertebrochondral ribs. Ribs 11 and 12 do not connect with the sternum and are called floating ribs.
