Bones

I sit at the top of your torso, a horizontal rod for your shoulders. I'm one of the most commonly broken bones, especially in a fall. What am I?

I'm a small, flat bone that protects your knee joint. I help your leg bend and straighten, but I'm not attached to any other bones with a joint. What am I?

I am the longest, strongest bone in your entire body. I am found in your thigh, connecting your hip to your knee. What am I?

I lie flat and centered, protecting the heart and lungs with my bony shield. Your ribs connect to me, creating a strong cage for your vital organs. What am I?

I'm a collection of small bones, numerous and nimble. I help you grasp, point, and play. What am I?
