Pancreatic disease exist as both congenital and acquired diseases. Two of the well known types of congenital defect are: Pancreatic divisum, where the pancreatic duct fails to form, and Annular pancreas, where extra pancreatic tissue grows and wraps around the duodenum leading to obstruction by constriction. [5]
In addition, the liver, pancreas, and biliary apparatus develop as outgrowths of the endodermal epithelium of the upper part of the duodenum. Since the upper part of the foregut is divided by the tracheoesophageal septum into the esophagus posteriorly and the trachea and lung buds anteriorly, deviation of the septum may result in abnormal ...
During development, differential growth of the wall of the stomach causes it to rotate to the left, and the liver and stomach undergo a lot of growth. This makes the two parts of the pancreas rotate around the duodenum. They then fuse; the dorsal pancreatic bud becomes the body, tail, and isthmus of the pancreas. The isthmus (also called the ...
The complete human digestive system is made up of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver and gallbladder). [5] The tract may also be divided into foregut, midgut, and hindgut, reflecting the embryological origin of each segment.

Exocrine pancreatic insufficiency (EPI) is the inability to properly digest food due to a lack or reduction of digestive enzymes made by the pancreas.EPI can occur in humans and is prevalent in many conditions [1] such as cystic fibrosis, [2] Shwachman–Diamond syndrome, [3] different types of pancreatitis, [4] multiple types of diabetes mellitus (Type 1 and Type 2 diabetes), [5] advanced ...
The pancreas is a large organ behind the stomach that produces digestive enzymes and a number of hormones. [1] There are two main types: acute pancreatitis, and chronic pancreatitis. [1] Signs and symptoms of pancreatitis include pain in the upper abdomen, nausea and vomiting. [1] The pain often goes into the back and is usually severe. [1]
[1] [5] By expressing sonic hedgehog (Shh) or Indian hedgehog (Ihh), the growth of both dorsal and ventral buds from the foregut endoderm is repressed to a large extent, inhibition of Shh or Ihh signaling pathway favor the pancreatic development. [6] The Homeodomain protein HB9 (Hlxb9) is critical for the formation of the dorsal bud, however it ...
