what is the name of the cell type responsible for insulin production?

The cell type that produces insulin is the pancreatic beta cell (also called β-cell). These cells reside in the islets of Langerhans within the pancreas and are the body's exclusive source of insulin production and secretion in mammals. Insulin helps regulate blood glucose by promoting cellular uptake of sugar and coordinating its storage and use. Amylin, another hormone co- produced by beta cells, is stored and released alongside insulin.
