intervertebral disc are correct EXCEPT:

Back
C. The discs play a major role in development of the curvature of the vertebral column
Corrected Explanation:
- A. During aging, the fluid within the nucleus pulposus is diminished, and the amount of fibrocartilage is increased: This is true. Aging causes dehydration of the nucleus pulposus and an increase in fibrocartilage(Arthur F. Dalley, Anne …)(Trans-Notes-Back-Muscles).
- C. The discs play a major role in the development of the curvature of the vertebral column: While intervertebral discs influence spinal flexibility and curvature maintenance, they do not develop the primary or secondary curvatures. Primary curvatures (thoracic and sacral) are embryonic, and secondary curvatures (cervical and lumbar) form due to changes in posture(Arthur F. Dalley, Anne …)(Trans-Notes-Back-Muscles).
- D. The discs are the thickest in the lumbar region: This is true, as lumbar discs support the most weight(Arthur F. Dalley, Anne …)(Trans-Notes-Back-Muscles).
