Finger phalanges

Looks like

Fourteen short bones in the fingers — three in each finger, two in the thumb — joined by small hinge joints.

What it does

Give the fingers their length and let them curl to grip and pinch.

A finger that looks rotated or overlaps another when making a fist after an injury is a displaced fracture needing care within days.
