Study Notes
Pancreas Structure and Function
- The pancreas is connected to the liver via the common bile duct.
- The pancreas is located in the abdominal cavity, behind the stomach.
Pancreatic Islets (Islets of Langerhans)
- The pancreatic islets, also known as the islets of Langerhans, account for approximately 1-2% of the total pancreas.
- The pancreatic islets are responsible for producing several hormones that regulate various bodily functions.
Hormones Produced by the Pancreas
- Glucagon, secreted by the Alpha cells, increases blood sugar levels by breaking down glycogen in the liver and stimulating gluconeogenesis.
- Insulin, secreted by the Beta cells, promotes the movement of glucose, proteins, and lipids out of the blood and into tissues, thereby lowering blood sugar levels.
- Somatostatin, secreted by the Delta cells, primarily regulates other endocrine cells of pancreatic islets by inhibiting the secretion of glucagon, insulin, and pancreatic polypeptide.
- Pancreatic polypeptide, secreted by the Pancreatic polypeptide cells, influences gastrointestinal motility and the feelings of hunger and fullness.
- Ghrelin, secreted by the Epsilon cells, stimulates the hypothalamus to boost appetite.
- Insulin promotes the synthesis of proteins and lipids, increases the cell's metabolism, and is essential for growth and repair.
General Terms
- The term "exocrine" is used to describe substances being excreted through a duct.
Pancreas Shape and Size
- The head of the pancreas is shaped like a hook.
- The pancreas is approximately 6 inches (15 cm) long.
