Enteric Nervous System

The enteric nervous system is sometimes called the 'second brain.' The enteric nervous system is a network of nerves in the gut with a direct connection to the brain. The colon's independent neural system means it does not reliably respond to conscious commands. The autonomic nervous system has three branches, including the enteric nervous system. What happens in the gut directly affects the brain through the enteric nervous system. The colon has its own nervous system that is sometimes called the second brain. Attempts to stop bowel movements may not prevent them from continuing. Attempts to initiate bowel movements may not cause them to occur on command.
