What are the main spinal regions?

The main spinal regions consist of five distinct segments: cervical, thoracic, lumbar, sacrum, and coccyx. Each region has unique characteristics and functions.

The cervical region is located at the top of the spine and consists of seven vertebrae (C1 to C7), which support the head and allow for a wide range of motion. The thoracic region follows and comprises twelve vertebrae (T1 to T12) that are attached to the ribs and play a crucial role in protecting the heart and lungs.

Next is the lumbar region, which includes five vertebrae (L1 to L5) that bear much of the body’s weight and are critical for mobility and flexibility in the lower back. The sacrum consists of five fused vertebrae (S1 to S5) and connects the spine to the hip bones. Finally, the coccyx, or tailbone, is made up of three to five fused vertebrae and serves as an attachment site for ligaments and muscles.

The other options contain inaccuracies. The inclusion of "pelvic" suggests multiple regions of the spine, which is not standard anatomical terminology. The term "dorsal" typically refers to the thoracic region in some
