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

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
between two vertebrae.

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.
intervertebral foramen

When the PLE test is conducted, lumbar spinal extension is strong, leading to tension in the anterior longitudinal ligament or the fibrous ring of the intervertebral disk and relaxation in the zygapophyseal capsule, to which surrounding mechanoreceptors or nociceptors react strongly and induce lumbar pain.
date of birth 11/12/1952 in Clausthal-Zellerfeld, internationally known due to his development of micro-therapy, micro-operations with intervertebral disks and tumors as well as the world's first operation on open nuclear spin tomographs (1988).
This model was then utilized to estimate net moments and compression and shear forces occurring at the L5-S1 spinal intervertebral disk during testing.
