Transgender hormone therapy (male-to-female) hair becomes more typically female in pattern. Lower leg hair becomes less dense. All of these changes depend to some degree on genetics. Head hair may change slightly in texture, curl, and color. This is especially likely with hair growth from previously bald areas. Eyebrows do not change because they are not androgenic. The lens of the eye changes in curvature. Because of decreased androgen levels, the meibomian glands (the sebaceous glands on the upper and lower eyelids that open up at the edges) produce less oil. Because oil prevents the tear film from evaporating, this change may cause dry
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
