What nerves control the heart beat?

Where does the interneuron do its job?
The central nervous system is designed to connect sensory and motor pathways for reflexes.Interneurons are the cells that serve as that connection. Interneurons (also known as association neurons) are neurons that are found only in the central nervous system. That means that they are found in the brain and spinal cord and not in the peripheral parts of the nervous system. There are more than 100 billion interneurons in the human body.
