Monday: Muscles move bones

Rocket lifts a book high. "Bones did that!"

Raven asks, "What do you notice when you lift?"

Nova hums. "Bones need a helper to move," she says.

Meet your muscles

Bones hold your body up.

But bones cannot move on their own.

Muscles move them!

Your body has more than 600 muscles.

A muscle pulls on a bone.

Then the bone moves.

Tendons hold on tight

A tendon is a strong cord.

It joins a muscle to a bone.

The muscle pulls the tendon.

The tendon pulls the bone along.

Muscles stretch across joints, where two bones meet.
