How is histology used to identify the pancreas?
Pancreatic Islets are spherical clusters of polygonal endocrine cells. On a pancreas histological slide stained with H&E, they appear as large, pale-staining cells enveloped by intensely staining, basophilic pancreatic acini.
What is the histological structure of pancreas?
Histological structure of pancreas. The pancreas was divided into two parts; exocrine pancreas (pancreatic acini and duct system) and endocrine portion (islets of Langerhans). The pancreas was encapsulated by thin connective tissue capsule which contained fine collagen fibers and also between acini (Fig. 2A).
What is the anatomical location of pancreas?
Anatomy of the pancreas The pancreas is an elongated, tapered organ located across the back of the belly, behind the stomach. The right side of the organ—called the head—is the widest part of the organ and lies in the curve of the duodenum, the first division of the small intestine.
What is the pancreatic duct histology?
They have flattened cuboidal epithelium that extends up into the lumen of the acinus to form what are called centroacinar cells. The smaller forms have a cuboidal epithelium, while a columnar epithelium lines the larger ducts. Intralobular ducts transmit secretions from intralobular ducts to the major pancreatic duct.
What are the anatomical relation in pancreas?
The neck of the pancreas lies in front of the superior mesenteric vein, splenic vein and portal vein junction. The body and tail of the pancreas run obliquely upward to the left in front of the aorta and left kidney. The pancreatic neck is the arbitrary junction between the head and body of the pancreas.
What are the cells present in pancreas?
The pancreatic islet cell types include alpha cells, which produce glucagon; beta cells, which produce insulin; delta cells, which produce somatostatin; and PP cells, which produce pancreatic polypeptide.
Which part of pancreas is intraperitoneal?
pancreatic tail
The pancreas is separated from the stomach anteriorly by the lesser sac of the peritoneal cavity. The pancreatic tail courses in the splenorenal ligament along with the splenic vessels, rendering this portion of the pancreas intraperitoneal.
What are the pancreatic ducts?
The pancreatic duct, or duct of Wirsung (also, the major pancreatic duct due to the existence of an accessory pancreatic duct), is a duct joining the pancreas to the common bile duct. This supplies it with pancreatic juice from the exocrine pancreas, which aids in digestion.
Is the pancreas intraperitoneal or retroperitoneal?
The pancreas is a retroperitoneal organ with a close anatomic relationship to the peritoneal reflections in the abdomen, including the transverse mesocolon and the small bowel mesentery, and is directly contiguous to peritoneal ligaments such as the hepatoduodenal ligament, gastrohepatic ligament, splenorenal ligament.
