What part of the autonomic nervous system causes an increase in digestive tract mobility?
Stimulation of the Parasympathetic nervous system causes an increase in digestive tract mobility. When stimulated the parasympathetic post-ganglionic neurons release a hormone called Acetylcholine.

Counteracting this increase in digestive tract mobility is the sympathetic nervous system, which releases a hormone called noradrenaline which slows down the digestive tracts contractions. This is how the Parasympathetic Nervous System gets the name "rest and digest"
