The majority of the islets of Langerhans cells are which type?

The main idea here is which cell type makes up most of the islets of Langerhans. The insulin-secreting beta cells are the most numerous, forming the bulk of the islet cell mass. Their primary role is to release insulin in response to rising blood glucose, promoting glucose uptake into tissues and lowering blood sugar after meals. Alpha cells, which secrete glucagon to raise blood glucose during fasting, are present but fewer in number. Delta cells produce somatostatin and are even less numerous, and PP (pancreatic polypeptide) cells are the smallest group, regulating pancreatic and gastrointestinal functions. Because beta cells predominate, their insulin output largely defines the islet’s endocrine activity.
