The nucleus pulposus is best described as which of the following?

• A. Gelatinous like substance in the disc.
• B. Bone in the back.
• C. Cartilage near part of the disc.
• D. Ligament between the disc.

Answer: (A)

The nucleus pulposus is the soft, gelatinous center of the intervertebral disc. It’s rich in water and proteoglycans, giving it a gel-like consistency that allows it to absorb and distribute compressive forces across the disc. This property helps protect the surrounding ring of fibrous tissue (the annulus fibrosus) and enables the spine to handle loads and movement. It is not bone, nor cartilage, nor a ligament—the nucleus pulposus is a distinct gel-like tissue inside the disc.
