Select the correct option.
1. | There are seven pairs of vertebrosternal, three pairs of vertebrochondral and two pairs of vertebral ribs. |
2. | 8th, 9th and 10th pairs of ribs articulate directly with the sternum. |
3. | 11th and 12th pairs of ribs are connected to the sternum with the help of hyaline cartilage. |
4. | Each rib is a flat thin bone and all the ribs are connected dorsally to the thoracic vertebrae and ventrally to the sternum. |
Out of ‘X’ pairs of ribs in humans only 'Y' pairs are true ribs. Select the option that correctly represents values of X and Y and provides their explanation:
1. | X=12, Y=5 True ribs are attached to vertebral column and sternum on the two ends. |
2. | X=24, Y=7 True ribs are dorsally attached to vertebral column but are free on ventral side. |
3. | X=24, Y=12 True ribs are dorsally attached to vertebral column but are free on ventral side. |
4. | X=12, Y=7 True ribs are attached dorsally to vertebral column and ventrally to the sternum. |
