==Regulation & Control==
==Regulation & Control==
*
*The functions of the small (and large) intestine are regulated by three elements:
**Endocrine hormones
**Paracrine hormones
**Neural transmitters
*Control is mainly local, with superimposed co-ordination through the ANS.
*All signals affect the small intestine via sensory neurones.
**The sensory neurones interact with the two plexuses in the intestinal wall.
**Sensory neurones in the myenteric plexus produce changes in muscle contractility
**Sensory neurones in the submucosal plexus produce changes in secretion and blood flow to the small intestine
**Plexuses are connected via interneurones
