Unit 3 Lab Project: Build A Moveable Limb

Introduction: This is a model of a moveable elbow built out of construction paper and metal brads that connected the bicep to the anterior band. The parts that are found in the model are bones, tendons, and muscles. Each one of these allow it to bend and contract.

Conclusion: By building a model I have learned about how bones, tendons and muscles allow our bodies to move a certain way. In certain different parts of the body bones, muscles and tendons can aid in supporting and protecting our bodies. The elbow works simular to a hinge because it bends and straightens. All the nerves that travel down the arm pass through the elbow and these nerves carry signals from the brain to the muscles and this makes the arm move. The elbow is what provides stability as we position our forarm to use our hand.
