The intervertebral disc space is typically defined on an X-ray photograph as the space between adjacent vertebrae.

The disc is actually grown together with the adjacent vertebrae and can be squeezed, stretched and twisted, all in small degrees.

Two convex facets from the head attach to two adjacent vertebrae.

In the spine, similar fibres join the intervertebral disk to the adjacent vertebrae.

Protrusions of the disc into the adjacent vertebra are known as Schmorl's nodes.

Metal plates can be screwed into the bone, joining adjacent vertebrae.

A spinal disc can be removed and the adjacent vertebrae fused.

The infection then spreads from two adjacent vertebrae into the adjoining intervertebral disc space.

Spinal fusion is an example of adjacent vertebrae connected allowing them to grow together into one piece.

Bone, metal plates, or screws can be used to make a bridge between adjacent vertebrae.
