The definition of nucleus pulposus is which of the following?

Explanation:
The nucleus pulposus is the soft, gel-like center of an intervertebral disc. It’s rich in water and proteoglycans, giving it a hydrated, jelly-like consistency that lets the disc absorb and distribute compressive forces when you stand, bend, or lift. This core sits inside the tougher outer ring called the annulus fibrosus, which helps contain it. It’s not bone (that would be the vertebral bodies), not the outer fibrous cartilage ring itself, and not a ligament between vertebrae. So the defining feature is the gelatinous, jelly-like substance at the disc’s center.
