Palm

Looks like

Thick, hairless skin with ridges and deep creases, anchored firmly to the tissue beneath.

What it does

Grips without slipping, and sweats a little to grip better; very rich in touch receptors.

Keeping it well

Calluses are protection, not illness. A deep cut here can reach tendons and nerves: move the fingers and get it seen.
