Module 7: Figure stomach structure
Neural and endocrine control of stomach acid secretion.
The stomach has three main regions: fundus, body and antrum. The two boxes on the left are expanded on the right to illustrate the neural and endocrine cells that regulate the function of the stomach. ACh, acetylcholine; GRP, gastrin-releasing peptide; Hist, histamine; PACAP, pituitary adenylyl cyclase-activating peptide (PACAP); Sst, somatostatin.
