  1. 4. What direction of movement does the annulus fibrosus limit whilst providing a strong bond between vertebrae.
  2. 7. Composed of water, type II collagen, chondrocyte-like cells, and proteoglycans, it forms the jelly centre of the disc.
  3. 9. Herniation usually affects this type of nerve root in the lumbar spine.
  4. 10. The outer portion of the disc.

  1. 1. The second stage of herniation also called a buldge, with slight impingement into the spinal canal.
  2. 2. The third stage where the nucleus breaks through the annulus, but remains within the disc.
  3. 3. In what direction is the nucleus most likely to herniate due to a lack of structural support from anterior and posterior longitudinal ligaments.
  4. 5. The rings made from collagen sheets that make up the Annulus Fibrosus.
  5. 6. The fourth stage where the nucleus lies outside the disc.
  6. 8. The fraction of the disc that is innervated.
  7. 11. The stage of herniatiation cause by disc degeneration associated with aging.
  8. 13. Intervertebral discs absorb this from vertical forces.
  9. 14. What pathology results from acute or chronic tearing of the annulus fibrosus
