The hindbrain has three parts including the cerebellum , the pons and the medulla oblongata.

The medulla is connected to the spinal cord and controls the unconscious body functions that are essential for living. These include breathing, swallowing, blood circulation and muscle tone. Above the medulla you will find the pons. Here the brainstem and the cerebellum are connected, this is able to happen because the pons acts as a bridge to connect them together. The pons does even more, it receives information from visual areas to control eye and body movements. Also, patterns of sleep and arousal are partially controlled by the pons. Information is relayed from the pons to the cerebellum to control the coordination of muscular movements and maintain equilibrium.
