Extrinsic (outside) are nerves from the brain (or spinal cord) to the digestive organ release two chemicals acetylcholine and adrenaline. Acetylcholine helps faster digestion by increasing the contraction of the digestive organs to squeeze with more forcefully and push the food through the digestive tract.he main nerves of the parasympathetic nervous system are the vagus nerves (tenth cranial nerves). PNS originates in the medulla oblongata; other parasympathetic neurons also extend from the brain and from the lower tip of the spinal cord.
The ANS controls digestive functions such as: secretion of saliva from the salivary glands, peristalsis to move food along the digestive tract, gastric acid production in the stomach, sphincter open and closing, hormone release from glands in the digestive system, and the storing energy in the form of fat.ntrinsic nerves within the walls of the esophagus, stomach, small intestine, and large intestine react when their walls are stretched by food. They cause the release of substances that speed up or slow down the movement of food, and the production of juices, by the digestive organs.
