Gastrointestinal hormones
The enteroendocrine cells are those endocrine cells that are located in the gastrointestinal system. They produce hormones and other signaling molecules that act on the brain and other parts of the body, in response to environmental changes in the digestive tract. Most of the cells in the tract are either specialized to absorb food and water or to release molecules into the gastronintestinal tract. Enteroendocrine cells space themselves among these other cells. More of them are found in the glands of the stomach and in the crevices of the intestine than anywhere else. Enteroendocrine cells of the intestine are the most numerous endocrine cells of the body. In a sense they are known to act as chemoreceptors, initiating digestive actions and detecting harmful substances and initiating protective responses. They produce gastrointestinal hormones or peptides in response to various stimuli and release them into the bloodstream for systemic effect, diffuse them as local messengers, or transmit them to the enteric nervous system to activate nervous Share to: D-cells, or Delta cells, can be found in the stomach, intestine, or Islets of Langerhans (the hormone producing regions of the pancreas which also produce glucagon and insulin …).  In the case of the enteroendocrine cells, these particular cells are present in the stomach and intestines. One more type of endocrine cells in the digestive tract, called the islets of Langerhans, are located in the pancreas. Most of the cells in the tract are either specialized to absorb food and water or to release molecules into the gastronintestinal tract. Enteroendocrine cells space themselves among these other cells. More of them are found in the glands of the stomach and in the crevices of the intestine than anywhere else. Gastric enteroendocrine cells are found in the gastric glands, mostly at their base. The G cells secrete gastrin, post-ganglionic fibers of the vagus nerve can release gastrin-releasing peptide during parasympathetic stimulation to stimulate secretion. They produce gastrointestinal hormones or peptides in response to various stimuli and release them into the bloodstream for systemic effect, diffuse them as local messengers, or transmit them to the enteric nervous system to activate nervous responses. Enteroendocrine cells. Another cell type in the stomach is the enteroendocrine cell. This cell is polarized in the opposite direction to that of the other gland cells. It lies at the base of the glands, underneath the chief or parietal cells. Its secretory granules face the blood vessels in the lamina propria. However, because of the long glands in the stomach lined by prominent cells, it may be hard to see, except just under the surface mucous cells. Gastric Pits. The portion of the gland lined by Surface mucous cells ends in a region called the GASTRIC PIT (foveolae). The pit opens up into the NECK area of the gland. From Wikipedia, the free encyclopedia. In anatomy, the G cell is a type of cell in the stomach and duodenum that secretes gastrin. It works in conjunction with gastric chief cells and parietal cells. G cells are found deep within the pyloric glands of the stomach antrum, and occasionally in the pancreas and duodenum. The vagus nerve innervates the G cells. Gastrin-releasing peptide is released by the post-ganglionic fibers of the vagus nerve onto G cells during parasympathetic stimulation Enteroendocrine cells are located in the stomach, in the intestine and in the pancreas. They produce gastrointestinal hormones or peptides in response to various stimuli and release them into the bloodstream for systemic effect, diffuse them as local messengers, or transmit them to the enteric nervous system to activate nervous responses. Enteroendocrine cells are those endocrine cells found int eh gastrointestinal tract. Enteroendocrine cells are present in the stomach and intestines. The endocrine system produces signaling chemicals for specific internal parts of the body. Most of the cells in the tract are either specialized to absorb food and water or to release molecules into the gastronintestinal tract. Enteroendocrine cells space themselves among these other cells. More of them are found in the glands of the stomach and in the crevices of the intestine than anywhere else.
