Anatom3DSciatic nerve
Nervus ischiadicus · Sedací nerv
Nervous system
Looks like
The thickest nerve in the body, as wide as a finger, running from the buttock down the back of the thigh.
What it does
Works the hamstrings, and moves and feels almost everything below the knee.
Keeping it well
Keep moving with sciatica and treat the cause; numbness in the saddle area with bladder trouble is an emergency.
