Document Summary

There is quite a bit of endocrine regulation of the git, both of its own activity, but also of things outside (cid:9675) (cid:9675) For example, ghrelin made by stomach makes you feel hungry, while leptin from adipose tissue make you feel full (induce satiety) As a side note, there is a lot of pharmaceutical companies working on products to mimic these hormones. There are a few differences between traditional endocrine systems and the git"s endocrine system (cid:9675) If you consider any endocrine organ, like the anterior pituitary gland, the thyroid and parathyroid, the adrenal glands, (cid:9675) (cid:9675) (cid:9675) They are all discrete units, with many endocrine cells clumped together into an organ with very distinctive tissue. This is not how the git"s endocrine system works. Rather, the secretory cells are greatly scattered in the mucosa. They do not form aggregates of secretion centres (cid:8226)
