Choose the number of correct statements using the diagram given below: There are 24 ribs in the human body. Each rib is a thin flat bone connected ventrally to the vertebral column and dorsally to the sternum. Thoracic vertebrae, ribs and sternum together form the rib cage.

Step-by-step solution

There are 12 pairs of ribs. Each rib is a thin flat bone connected dorsally to the vertebral column and ventrally to the sternum. It has two articulation surfaces on its dorsal end and is hence called bicephalic. First seven pairs of ribs are called true ribs. Dorsally, they are attached to the thoracic vertebrae and ventrally connected to the sternum with the help of hyaline cartilage. The 8th, 9th and 10th pairs of ribs do not articulate directly with the sternum but join the seventh rib with the help of hyaline
