Dr Mike discusses the functional anatomy of the pancreas, including how certain hormones stimulate Acinar cells to release pancreatic juices and how ductal c...
The pancreas is an organ located in the abdomen. It plays an essential role in converting the food we eat into fuel for the body's cells. The pancreas has tw...
Although it is primarily an exocrine gland, secreting a variety of digestive enzymes, the pancreas also has endocrine cells. Its pancreatic islets —clusters of cells formerly known as the islets of Langerhans—secrete the hormones glucagon, insulin, somatostatin, and pancreatic polypeptide (PP).
1 Μαΐ 2023 · The pancreas is a composite organ, which has exocrine and endocrine functions. The endocrine portion is arranged as discrete islets of Langerhans, which are composed of five different endocrine cell types (alpha, beta, delta, epsilon, and upsilon) secreting at least five hormones including glucagon, insulin, somatostatin, ghrelin, and ...
3 Οκτ 2022 · The islets of Langerhans are clusters of pancreatic cells discovered by Dr. Paul Langerhans, a pathologist who also discovered the dendritic Langerhans cells in 1869. [1] Each islet contains up to a few thousand endocrine cells, and the islets constitute up to 2% of the total pancreatic mass.
The pancreatic islets are small islands of cells that produce hormones that regulate blood glucose levels. Hormones produced in the pancreatic islets are secreted directly into the bloodstream by five different types of cells. The alpha cells produce glucagon, and make up 15–20% of total islet cells.
