Cauda equina

Looks like

A sheaf of nerve roots hanging below the end of the cord at about the first lumbar vertebra, like a horse's tail.

What it does

Carries nerves to the legs, bladder, bowel and genitals.

Keeping it well

Numbness in the saddle area, new trouble passing or holding urine, or weakness in both legs with back pain is an emergency — same day.
