ENTERIC NERVOUS SYSTEM
Central Nervous System (CNS)• brain & spinal cord• integrative & control centers
Peripheral Nervous System (PNS)• cranial nerves & spinal nerves• communication between CNS & body
Somatic Nervous System• somatic motor (voluntary)• conducts impulses from CNS -->
skeletal muscles
Autonomic Nervous System (ANS)• visceral motor (involuntary)• conducts impulses from CNS --> cardiac
muscles, smooth muscles, glands
Sympathetic Division (SNS)• “fight or flight”• mobilizes body during activity
Parasympathetic Division (PSNS)• “rest and digest”• promotes “housekeeping” functions at rest
Enteric Division (ENS)• handles digestion• local, autonomous function; largely
independent of CNS
= incoming / sensory / afferent
= outgoing / motor / efferent

THE BIG IDEA
The gut has its own nervous system that acts largely independently of the brain; the gut “thinks for itself ”
No other part of the nervous system can do this
The gut influences the brain in the head far more than vice versa
The gut plays a role in psychological state and in sorting out social dominance
WARNING: gut feelings are not always accurate! More on this in future sessions.

FIELDWORK
What do you see about the intelligence of the gut that you didn’t see before?
How does this knowledge add to your understanding of embodiment?
Drawing on your own experience, how would explain the intelligence of the gut (or heart) as distinct from the intelligence of the brain in your head?
