islet /is·let/ (-lit) an island.

islets of Langerhans irregular microscopic structures scattered throughout the pancreas and comprising its endocrine portion. They contain the alpha cells, which secrete the hyperglycemic factor glucagon; the beta cells, which secrete insulin; the delta cells, which secrete somatostatin; and the PP (or F ) cells, which secrete pancreatic polypeptide. Degeneration of the beta cells is one of the causes of diabetes mellitus.

pl.n.

Irregular clusters of endocrine cells scattered throughout the tissue of the pancreas that secrete insulin and glucagon. Also called islands of Langerhans.
