What are the areas of the vertebrae classified into?

The classification of the areas of the vertebrae includes four specific regions: cervical, thoracic, lumbar, and sacral.

The cervical region consists of the first seven vertebrae (C1-C7) located in the neck. These vertebrae support the head and allow for a range of motion.

The thoracic region includes twelve vertebrae (T1-T12) that articulate with the ribs, providing structural support for the rib cage and protecting the heart and lungs.

The lumbar region consists of five vertebrae (L1-L5) in the lower back, which are larger and designed to bear heavier loads while allowing flexibility and movement.

Lastly, the sacral region is made up of five fused vertebrae (S1-S5) that form the sacrum, connecting the spine to the pelvis.

Together, these four areas represent the key regions of the vertebral column, each serving distinct structural and functional roles in the human body.
