The heart is a muscle with it's own ability to create electrical impulse via the sinoatrial node (SA node) that lies in the right atrium. The impulses generated by the SA node are very regular and constant. However, the SA node can be sped up or slowed down by autonomic nerve impulses that come from the brainstem. The brainstem is told how to change the heart rate by information from the hypothalamus. Thus, although the heart controls its own heartbeat, it can be modified as necessary under the control of the brainstem and hypothalamus.
The reticular formation is a network of neurons located in the brainstem. It is involved in regulating arousal, attention, and sleep-wake cycles.
The medulla oblongata is the the most caudal portion of the brain step just superior to and continuous with the spinal cord proper. It is part of the nervous system.
Structures that are not part of the diencephalon include the cerebellum, brainstem, and cerebral cortex.
The cerebellum is located inferior to the cerebrum and posterior to the brainstem. It plays a key role in motor control, coordination, balance, and posture.
The respiratory control centers in the brain are primarily located in the medulla oblongata and pons, which are part of the brainstem. These regions regulate the rate and depth of breathing to maintain appropriate levels of oxygen and carbon dioxide in the body.

The medulla oblongata is the part of the brainstem that contains nerve centers that control vital processes such as heart rate, breathing, blood pressure, and reflexes like swallowing and vomiting. It plays a crucial role in maintaining homeostasis and ensuring the body's survival.
