Median nerve

Looks like

A nerve running down the middle of the arm and through the tight tunnel at the wrist.

What it does

Feels the thumb side of the hand and works the muscles of the thumb pad.

Keeping it well

Wrist splints at night and a neutral keyboard; numbness that wakes you is carpal tunnel and is treatable.
