Left little finger

Looks like

The fifth digit, the shortest finger: three phalanges on the fifth metacarpal.

What it does

Adds strength to grip, especially power grip, and helps hold objects across the palm.

Keeping it well

A bent-down knuckle after a punch is a 'boxer's fracture'. Contracture pulling it into the palm is usually Dupuytren disease.
