Answer 1

Correct Answer - Option 2 : 12

The Correct Answer is 12.

• Human ribs are flat bones that form part of the rib cage to help protect internal organs. Humans usually have 24 ribs, in 12 pairs.
• The first seven pairs are attached directly to the sternum by costal cartilages and are called true ribs. The 8th, 9th, and 10th pairs are called false ribs, they do not join the sternum directly but are connected to the 7th rib by cartilage.

• Human ribs are flat bones that form part of the rib cage to help protect internal organs. Humans usually have 24 ribs, in 12 pairs. Only 1 in 500 people have an extra rib known as a Cervical rib. 
• At the front of the body, most of the ribs are joined by costal cartilage to the sternum. Ribs connect to vertebrae at the costovertebral joints.
