The cerebellum is a cauliflower-shaped structure, located just above the brain stem, beneath the occipital lobes at the base of the skull. The cerebellum regulates muscle tone, coordinates movement and helps maintain posture and balance.he midbrain â the uppermost part â has fibers that connect the brain stem to the cerebrum and cerebellum; this area is very important in the control of skeletal movements. The pons, which lies between the midbrain and medulla oblongata, relays sensory information between the cerebrum and cerebellum.
