Skeleton
Looks like
A thin, tough membrane covering every bone except at the joints, rich in nerves and blood vessels.
What it does
Supplies blood to the bone, anchors tendons and makes new bone to heal fractures.
Keeping it well
It is why a bruised shin hurts so much. Bone pain at night that keeps getting worse needs investigation.
