Arteria radialis indicis

Looks like

A small artery from the radial artery (or its thumb branch) in the palm, running along the thumb side of the index finger.

What it does

Supplies the thumb side of the index finger.

Keeping it well

Can be damaged in cuts of the thumb web; the finger still has its other digital artery.
