The soft inner area of the intervertebral disc. This is gelatinous in consistency in young people and dries out as we age. It is surrounded by a tough fibrous shell called the annulus fibrosus.

Innermost gelatinous core of the intervertebral disc. It acts like a shock absorber for axial forces and like a semi-fluid ball bearing during flexion, extension, rotation, and lateral flexion of the vertebral column.

The core of the intervertebral disc. It has a high fluid content in our early years and then dries out with age.

The gel-like mass located at the center of intervertebral discs.

the soft inner core of the disc.

The soft, squishy and spongy inner portion of the intervertebral disc.

Soft center of an intervertebral disc, made up of gel-like substance.

The semi-gelatinous tissue in the center of an intervertebral disc. It is surrounded and contained by the annulus fibrosus which prevents this material from protruding outside the disc space.

Semi-gelatinous substance contained within the annulus fibrosus of the intervertebral disc. Internal derangement of the disc may result in leakage of the nucleus pulposus through the breached annular fibres. It is the nucleus pulposus (or remnants thereof) which is removed during a discectomy.

The gelatinous mass in the center of the intervertebral disc. Objective complaints— What the doctor finds by examination.

a soft, pulpy, highly elastic substance in the center of an intervertebral disc, a remnant of the notochord

Nucleus pulposus is the jelly-like substance in the middle of the spinal disc. It is the remnant of the notochord. It functions to resist compressive loads.
