Krause's glands the conjunctiva. Krause's glands are named after German anatomist Karl Friedrich Theodor Krause (1797–1868). Krause's glands Krause's glands are small, mucous accessory lacrimal glands that are found underneath the eyelid where the upper and lower conjuctivae meet. Their ducts unite into a rather long sinus which open into the fornix conjunctiva. There are approximately forty Krause glands in the region of the upper eyelid, and around 6 to 8 in the region of the lower lid. The function of these glands are to produce tears which are secreted onto the surface of the conjuctiva. There are rare instances of tumors
Gastric glands release of histamine is stimulated by the secretion of gastrin from the G cells. Histamine promotes the production and release of bicarbonate ions from the parietal cells to the blood and protons to the stomach lumen. When the stomach pH decreases(becomes more acidic), the ECLs stop releasing histamine. The G cells are mostly found in pyloric glands in the antrum of the pylorus; some are found in the duodenum and other tissues. The G cells secrete gastrin. The gastric pits of these glands are much deeper than the others and here the gastrin is secreted into the bloodstream not the
