Answer :
Final answer:
Cherry's balance on the balance beam is achieved through coordination between the semicircular canals and the cerebellum, which work together to manage balance and posture during the intricate movements of gymnastics.
Explanation:
Cherry's ability to maintain her balance on the balance beam best exemplifies the complex coordination between her semicircular canals and the cerebellum in her brain. When performing gymnastics on the balance beam, athletes like Cherry rely on their vestibular system, particularly the semicircular canals located in the inner ear, to regulate balance and spatial orientation.
These canals are filled with fluid and lined with tiny hairs that move with the fluid as the head changes position. This movement sends signals to the cerebellum, which is part of the brain responsible for coordinating voluntary movements, balance, and posture. Thus, as Cherry stands on the narrow surface of the balance beam, her body is continuously sending and receiving information through this intricate system to help her keep her equilibrium.
