Question

Sequence of regions of the vertebral column, starting from the skull is:
(A). Thoracic
(B). Cervical
(C). Sacral
(D). Lumbar

• A. (A), (B), (C), (D)
• B. (B), (A), (D), (C)
• C. (B), (A), (C), (D)
• D. (C), (B), (D), (A)

Hint:

Remember the sequence ”CTLS” for the vertebral column: Cervical, Thoracic, Lumbar, Sacral.

Answer 1

The Correct Option is B

The vertebral column is divided into the following regions in sequence from the skull:

• Cervical (B): The first seven vertebrae starting from the skull, labeled \(C1 \text{ to } C7\), support the neck.
• Thoracic (A): The next twelve vertebrae, labeled \(T1 \text{ to } T12\), are located in the upper back and connect to the ribs.
• Lumbar (D): The five larger vertebrae, labeled \(L1 \text{ to } L5\), are in the lower back and bear the body’s weight.
• Sacral (C): A group of fused vertebrae located at the base of the spine.

Hence, the correct sequence is Cervical, Thoracic, Lumbar, and Sacral.
