...it? Is it normal? In between my thumb and my index finger is a vein. When I point with my finger, and hold out my thumb (like children do to make the shape of a 'hand-gun' with their hand) there's a pulsing vein that is clearly seen. It's slightly dark, and I can still see it when my hand isn't in this position. It seems to be a big vein, placing my finger on it lets me feel my pulse. Is this normal? I think it's called the brachial artery, or vein?
