For the attachment of 8th, 9th and 10th ribs, which of the following cartilages are found?
| 1. | Hyaline | 2. | Elastic |
| 3. | Fibroelastic | 4. | Reticular |
| 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. | \(11^{\text {th }} \text{and} ~12^{\text {th }}~ \text {Pairs}\) |
Vertebrochondral ribs attach to the seventh rib with the help of:
| 1. | Elastic cartilage |
| 2. | Hyaline cartilage |
| 3. | Fibrous cartilage |
| 4. | White fibrous tissue |
| Assertion (A): | 11th and 12th pairs of ribs are called floating ribs. |
| Reason (R): | They do not have any connection with the sternum ventrally. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A) |
| 2. | Both (A) and (R) are true, but (R) is not the correct explanation of (A). |
| 3. | (A) is true, but (R) is false. |
| 4. | (A) is false, but (R) is true. |
In human body, which one of the following is anatomically correct ?
| 1. | Floating ribs-2 pairs |
| 2. | Collar bones-3 pairs |
| 3. | Salivary glands-1 pair |
| 4. | Cranial nerves-10 pairs |
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:
| X | Y | |
| 1. | 12 | 15 true ribs are attached dorsally to the vertebral column and sternum on the two ends |
| 2. | 24 | 7 true ribs are dorsally attached to the vertebral column but are free on the ventral side |
| 3. | 24 | 12 true ribs are dorsally attached to the vertebral column but are free on the ventral side |
| 4. | 12 | 7 true ribs are attached dorsally to the vertebral column and ventrally to the sternum |
| 1. | 7 pairs true ribs, 3 pairs false ribs, 2 pairs floating ribs |
| 2. | 8 pairs true ribs, 2 pairs false ribs, 2 pairs floating ribs |
| 3. | 7 pairs true ribs, 4 pairs false ribs, 1 pair floating ribs |
| 4. | 6 pairs true ribs, 4 pairs false ribs, 2 pairs floating ribs |
In rib case, which of the following set of ribs remain attached to each other?
| 1. | 2nd, 3rd and 4th pairs of the ribs |
| 2. | 4th, 5th and 6th pairs of the ribs |
| 3. | 7th, 8th and 9th pairs of the ribs |
| 4. | 8th, 9th and 10th pairs of the ribs |
| 1. | They articulate only with the sternum |
| 2. | They are connected to both the vertebrae and scapula |
| 3. | They have a dual blood supply |
| 4. | They have two articulation surfaces at the dorsal end |
