Want to be a Doctor

[DeerHunter53]

When I was young I decided I wanted to be a doctor, so I took the entrance exam to go to Medical School.
One of the questions was to rearrange the letters "PNEIS" into the name of an important human body part which is most useful when erect.

Guesses?

I see a couple better answers than mine. Guess I'm stuck in the sawmill the rest of my life.

Those who answered Spine are or should be doctors all of the rest of us are just sending emails.....
