• B. Man
• C. Both of the above
• D. None of the above

Answer 1

The correct option is C Both of the above

The rib cage appears like a bony basket formed by the sternum, thoracic vertebrae and in mammals, 12 pairs of ribs. The rib cage protects the internal organs of the chest. It also supports the chest wall, preventing it from collapsing. Each pair of ribs is attached dorsally to a separate vertebra. Of the 12 pairs of ribs, the first 7 are attached ventrally to the sternum, the next 3 are attached indirectly by cartilage and the last 2, the floating ribs, have no attachments to the sternum. The first 7 pairs of ribs are called as 'true ribs'. Their number is same in both man and rabbit.
