| 3. | Salivary glands-1 pair | 4. | Cranial nerves-10 pairs |
Which one of the following items gives its correct total number?
1. Floating ribs in humans - 4
2. Amino acids found in proteins - 16

| List-I | List-II | ||
| A. | Vertebrochondral Ribs | I. | IIum , Ischium Pubis |
| B. | Floating Ribs | II. | \(8^{\text {th }}, 9^{\text {th }} \text {and} ~10^{\text {th }} \text{Pairs}\) |
| C. | Scapula | III. | Acromion |
| D. | Coxal Bone | IV. | \(11^{\text {th }} \text{and} ~12^{\text {th }}~ \text {Pairs}\) |
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. |
