Document Summary
Digestive system lectures: compare and contrast the effects of the sympathetic and parasympathetic innervation (the gi innervation learning exercise will help you with this. ) Constriction (close: be familiar with all digestive system structures. Inside body wall of stomach: parietal peritoneum, covering internal organs: visceral peritoneum, periotinal cavity: in btw prior layers. Mesentary proper: fold of peritoneum extends from posterior abdominal wall to cover small intestine.
