Joints & cartilage
Looks like
The soft, gel-like core of the disc between T12 and L1 in the chest, sitting slightly behind the disc's centre inside a ring of tough fibres.
What it does
Mostly water held in a gel; it spreads load evenly across the vertebrae and acts as the pivot on which this level bends.
Keeping it well
Sits at the end of the spinal cord (conus); a large rupture here can affect legs, bladder and bowel together, an emergency.
