What is the maximum number of common ligaments identified with the vertebral couple?
What is the resin that nine common ligaments are identified but only eight will be attached at any specific vertebral couple?
the ligamentum nuchae and supraspinous ligaments attach to the spinous tubercles, but only one of these will be identified at a single vertebral couple
What is the number of true intervertebral discs identified in the adult?

cervical...22-25%; thoracic...20%; lumbar...33%
What is the cervical nucleus pulposus composed of?
What is the water concentration in the lumbar nucleus pulpous at birth and after thirty?
What is the organizational pattern for glycosaminoglycans in the lumbar nucleus pulposus?
they typically lack a binding site for hyaluronic acid and are thus non-aggregated
What cell is associated with the nucleus pulposus until about age eleven?
