In order to maintain balance, the gymnast would need to see the balance beam and determine where her feet are touching it. She would need to control the muscle contractions in her body to ensure she doesn’t fall off the beam. The regions of the brain numbered above that are involved directly in maintaining balance are Answer, Answer, Answer, and Answer.
