is the enteric nervous system part of the autonomic nervous system
The enteric nervous system (ENS) or intrinsic nervous system is one of the main divisions of the nervous system and consists of a mesh-like system of neurons that governs the function of the gastrointestinal tract. It is now usually referred to as separate from the autonomic nervous system since it has its own independent reflex activity. The ENS is also called the second brain.
