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.

Test your knowledge on the anatomy of the pancreas, including its position, shape, surrounding tissues, and exocrine functions. Learn about the compound racemose gland and the secretion of pancreatic juice.
