What is the medical term used for a slipped disc?

• A. Herniated nucleus pulposus
• B. Degenerative disc disease
• C. Bulging disc
• D. Disc prolapse

Answer: (A)

The term "herniated nucleus pulposus" accurately describes a slipped disc. This condition refers specifically to the displacement of the inner gel-like material, known as the nucleus pulposus, of an intervertebral disc. When the outer layer, or annulus fibrosus, becomes weakened or torn, this inner substance can protrude or "herniate" out of its normal position. This herniation can lead to nerve compression and results in painful symptoms, often affecting the lower back or neck, depending on the location of the affected disc.

While "degenerative disc disease" refers to the overall degeneration of a disc over time rather than a specific event like a herniation, "bulging disc" is often used interchangeably with a herniated disc but does not denote the same underlying mechanism of nucleus pulposus displacement. "Disc prolapse" can refer to similar scenarios but is not the standard medical term used. Understanding these distinctions is vital for precise communication in medical contexts.
