all of the following statements are true of intervertebral disc problems, except: the most common sites for herniated disc problems are between the thoracic vertebrae. sciatica results from compression of the roots of the sciatic nerve. with age, intervertebral discs lose their water content and elasticity. discs contribute significantly to an individuals height. a herniated disc occurs when the nucleus pulposus breaks through the anulus fibrosis. i dont know yet

Explanation:

The most common sites for herniated - disc problems are between the lumbar vertebrae (L4 - L5 and L5 - S1) or the cervical vertebrae, not between the thoracic vertebrae. Sciatica is indeed caused by compression of the sciatic nerve roots. Intervertebral discs lose water content and elasticity with age. Discs contribute to height as they are part of the spinal column structure. A herniated disc occurs when the nucleus pulposus breaks through the anulus fibrosus.

Answer:

The most common sites for herniated disc problems are between the thoracic vertebrae.
