intervertebral disk

A pad of fibrocartilage between the articular surfaces of two successive vertebral centra which has nucleus pulposus at its core. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the intervertebral disk is

A pad of fibrocartilage between the articular surfaces of two successive vertebral centra which has nucleus pulposus at its core. The atlas records it as a cartilage at the organ scale in the human body.

Where the intervertebral disk is

It sits within the skeletal system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the intervertebral disk connects to

The atlas records 9 typed relationships for it, across 5 kinds of connection. part of intervertebral joint.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the intervertebral disk. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as discus intervertebralis, intervertebral disc, spinal disc, intervertebral fibrocartilage and spinal disk. Searching any of those names reaches this page.

Questions

Where is the intervertebral disk?

It sits within the skeletal system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the intervertebral disk connect to?

Part of: intervertebral joint.

Is the intervertebral disk the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
