Corticotropin-releasing hormone (CRH) is released by the paraventricular nucleus (PVN) of the hypothalamus.[2] It then acts on the anterior pituitary to release adrenocorticotropic hormone (ACTH), which subsequently acts on the adrenal …
WebDec 1, 2002 · The ionic mechanism (K ATP channel-dependent) of stimulus-secretion coupling in the pancreatic β-cell. 1: Glucose enters the β-cell via GLUT2 transporters. 2: It is metabolized to produce an increase in the intracellular ATP-to-ADP ratio. 3: This results in closure of K ATP channels. 4: This also results in membrane depolarization. WebGastric secretion is stimulated by the act of eating (cephalic phase) and the arrival of food in the stomach (gastric phase). Arrival of the food in the intestine also controls gastric secretion (intestinal phase). The secreted fluid contains hydrochloric acid, pepsinogen, intrinsic factor, bicarbonate, and mucus.
