JOINTS AND BONES.
ITTLE girls like a jointed doll to play with, because they can bend such a doll in eight or ten places, make it stand or sit, or can even play that it is walking.
Jointed dolls.
As you study your own bodies to-day, you will find that you each have better joints than any dolls that can be bought at a toy shop.
HINGE-JOINTS.
Some of your joints work like the hinges of a door, and these are called hinge-joints.
You can find them in your elbows, knees, fingers, and toes.
