Answer :
The regions of the brain involved directly in maintaining balance and posture for the gymnast include the cerebellum, the somatosensory cortex, and the motor cortex.
- Cerebellum: Responsible for coordinating voluntary movements, balance, and posture by integrating sensory inputs and fine-tuning motor activities.
- Somatosensory cortex: Processes sensory information from the body, such as touch and proprioception, which helps the gymnast determine where her feet are on the balance beam.
- Motor cortex: Controls voluntary muscle contractions and sends signals to the muscles to adjust movements and maintain balance.
Complete question:
A gymnast is able to maintain a steady posture while on a balance beam. 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 and posture are?
