What is the primary substance produced by delta cells in the pancreas?

The primary substance produced by delta cells in the pancreas is somatostatin. Delta cells are one of the types of endocrine cells found in the islets of Langerhans within the pancreas. Somatostatin plays a crucial role in regulating various physiological processes in the body. Specifically, it inhibits the release of several hormones, including insulin and glucagon, thereby serving as a regulator of glucose metabolism. By balancing the actions of other hormones, somatostatin helps maintain homeostasis within the endocrine system.

In contrast, insulin and glucagon are produced by beta and alpha cells, respectively, and are primarily involved in controlling blood sugar levels. Pancreatic amylase is an enzyme secreted by the pancreas that aids in the digestion of carbohydrates, but it is not produced by delta cells. The specific role of somatostatin underscores its importance in the overall function of the pancreas and endocrine regulation.
