intervertebral disc

A broad disk of fibrocartilage situated between adjacent vertebrae of the spinal column.

intervertebral disk

one of the fibrous, broad, and flattened disks found between adjacent spinal vertebrae, except the axis and the atlas. The disks vary in size, shape, thickness, and number, depending on the location in the back and the particular vertebrae they separate.

Intervertebral disk

Cylindrical elastic-like gel pads that separate and join each pair of vertebrae in the spine.

intervertebral disk
the pad of fibrocartilage between the bodies of adjoining vertebrae made up of a pulpy center surrounded by a series of concentric fibrous rings. It is subject to degeneration, extrusion, protrusion and herniation resulting in the development of intervertebral disk disease (see below) known in humans as slipped disk.
intervertebral disk disease
the syndrome of pain and neurological deficits, sometimes complete paralysis, resulting from displacement of part or all of the nucleus of an intervertebral disk. Seen most often in dogs, particularly those of chondrodystrophoid breeds such as Dachshund, Basset hound and Beagle. The most frequently involved disks are in the thoracolumbar region from T11 to L2, but those in the cervical and lumber spine are also commonly affected. See also hansen's classification.
intervertebral disk space
the space between vertebrae occupied by an intervertebral disk as seen on radiographs.

The first main difference is their location because they are present within the center of the intervertebral disk, rather than within the vertebral body.
