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.
In the rest of the GI tract, it consists. of smooth muscle (three layers in the stomach, two layers in the small and large. intestines) and associated nerve fibers. The smooth muscle is responsible for. movement of food by peristalsis and mechanical digestion by segmentation. In some. regions, the circular layer of smooth muscle enlarges to form sphincters, circular. muscles that control the opening and closing of the lumen (such as between the. stomach and small intestine).
