Clinical Relevance
Any damage or disorder in the Annulus Fibrosus and Nucleus Pulposus can cause:
- Herniated Disc: A common condition where the nucleus pulposus protrudes through the annulus fibrosus often the causing pain and nerve compression.
- Degenerative Disc Disease: The age-related changes in the annulus fibrosus and nucleus pulposus can lead to the disc degeneration impacting spinal function.
Difference Between Annulus Fibrosus and Nucleus Pulposus
The primary difference between annulus fibrosus and nucleus pulposus lies in their respective positions within an intervertebral disc. The annulus fibrosus occupies the outer region of the disc while the nucleus pulposus resides within the disc’s inner core. The vertebral column serves as a protective structure for the spinal cord running along its central cavity.
The annulus fibrosus constitutes the outer layer of the intervertebral disc consisting of the collagen and protein-rich lamellae. In this article, we will study the difference between annulus fibrosus and nucleus pulposus, what annulus fibrosis and nucleus pulposus is, the similarities between annulus fibrosis and nucleus pulposus, and their clinical relevance.
