Term: Parasympathetic Division of the ANS

“One of the two subdivisions of the ANS, having cell bodies of pre-ganglionic neutrons in nuclei in the brain stem and in the lateral grey horn of the sacral portion of the spinal cord; primarily concerned with activities that conserve and restore body energy.” (1)  In a nutshell, you are in a parasympathetic state, when you are in a relaxed state of mind and body or in a “rest and digest” mode.
