In intervertebral disc disease, the degenerated nucleus propulsus is located in fibrocartilage separating what part of adjacent vertebrae?

In intervertebral disc disease, the nucleus pulposus, which is the gel-like center of the intervertebral disc, is surrounded by the annulus fibrosus. The intervertebral discs serve as cushions between the bodies of adjacent vertebrae, providing support and allowing for flexibility in the spine. The degenerated nucleus pulposus is located within a fibrocartilaginous structure that separates the bodies of the vertebrae.

This anatomical relationship is crucial for understanding how intervertebral disc disease can lead to issues such as herniation, where the nucleus pulposus may bulge out and compress surrounding spinal nerves. Understanding the significance of the intervertebral disc's placement between the vertebral bodies helps with recognizing the potential impact of disc degeneration on the overall function and health of the spine.
