A man is suffering from lower-back pain. Which region of the vertebral column might be affected? (A) Cervical region, (B) thoracic region, (C) lumbar region, or (D) none of the answers is correct.

The vertebral column, which is also known as the backbone or spine, is the axis of the axial skeleton and protects the spinal cord. The cervical section of the vertebral column corresponds to the neck region and consists of seven vertebrae. The thoracic section, which corresponds to the back of the chest, is made of 12 vertebrae. Each of them is attached to one pair of ribs. Then there are five lumbar vertebrae that are thick and sturdy. They make the curve of the lower back. Next, five fused sacral vertebrae connect the bones of the pelvis. Lastly, four tiny bones are fused to form the coccyx, also known as the tailbone.

We can presume that if a man is suffering from lower-back pain, the lumbar region of his vertebral column is probably affected. The correct answer is thus (C) lumbar region.
