Out of ' \(X\) ' pairs of ribs in humans, generally ' \(Y\) ' pairs are floating ribs. Select the option that correctly represents values of ' \(\mathrm{X}\) ' and ' \(\mathrm{Y}\) ' and provides the explanation.
Out of the 12 pairs of ribs, the last two (11th and 12th) pairs of ribs are not connected ventrally and are therefore, called floating ribs. True ribs (1st seven pairs) are ventrally connected to the sternum. The vertebrochondral ribs (8th, 9th and 10th pairs) of ribs do not articulate directly with the sternum but join the seventh rib with the help of hyaline cartilage.

Which one of the following is showing the correct sequential order of vertebrae in the vertebral column of human beings?
1 Cervical - lumbar - thoracic - sacral coccygeal
2 Cervical - thoracic - sacral - lumbar coccygeal
3 Cervical - sacral - thoracic - lumbar coccygeal
4 Cervical - thoracic - lumbar - sacral coccygeal
Explanation:
The vertebral column is differentiated into cervical (7), thoracic (12), lumbar (5), sacral (1-fused) and coccygeal (1-fused) regions starting from the skull.
