Study Notes
Pancreas Development
- The pancreas develops from two parts: the dorsal part (accessory pancreatic duct) and the ventral part (main pancreatic duct).
- Around the sixth week of gestation, the two parts meet and fuse, establishing a communication between their ducts.
Pancreas Anatomy
- The pancreas is a compound racemose gland with exocrine and endocrine functions.
- It is divided into four parts: head, neck, body, and tail.
- The head lies within the curve of the duodenum and is in contact with the inferior vena cava and portal vein.
- The uncinate process originates from the lower left portion of the head and lies posteriorly to the superior mesenteric vessels.
- The neck or isthmus connects the head to the body and is related to the origin of the portal vein.
Pancreas Location
- The pancreas is a medium retroperitoneal organ, slightly flattened and tapered.
- It is located transversally in front of the main vessels, at the level of the first or second lumbar vertebra.
Ultrasound Study of the Pancreas
- The study of the pancreas includes transverse, longitudinal, and angled oblique scan planes.
- The pancreas has a slightly oblique shape, extending left-upward, with the cephalic portion generally in a lower position compared to the body and tail.
- It lies against the vertebral column, which determines a slight curvature of the organ.
