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.
