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, from the skull downwards, comprises these sequential regions:

• Cervical (B): The first seven vertebrae (\(C1 \text{ to } C7\)), located below the skull, provide neck support.
• Thoracic (A): The subsequent twelve vertebrae (\(T1 \text{ to } T12\)) form the upper back, connecting to the ribs.
• Lumbar (D): Five larger vertebrae (\(L1 \text{ to } L5\)) in the lower back bear the body's weight.
• Sacral (C): Fused vertebrae located at the spine's base.

Thus, the sequence is Cervical, Thoracic, Lumbar, and Sacral.
