Introducing what pancreas anatomy entails
Studying the head as part of pancreas anatomy
The head is a flattened structure which is about two to three centimeters and includes the uncinate process. It is attached to the second and third region of the duodenum on the right side. It is traced to merge with the neck towards the left side. GDA insertion is found in the border between the head and the neck of the pancreas.
Studying the neck in regard to pancreas anatomy
The neck is about two and a half centimeters in length. Its superior borders are related to the pylorus structure of the stomach. It is from the inferior border of the head that the mesenteric vessels emerge. Splenic vein and SMV are found to confluence forming the portal vein in the posterior side of the neck. It is at the posterior side of the neck that you will find no branches connected to the pancreas.
Body and tail of the pancreas-pancreas anatomy
This is a long structure which appears to be elongated. Its anterior surface is separated from the stomach by the presence of lesser sac. Its posterior surface is related to the aorta of the heart as well as adrenal glands. Splenic vein is found to run deep in the posterior surface of the body very close to the posterior border. Transverse mesocolon covers the inferior surface of the body.
The tail is narrow and appears to be short segmented. It found in the twelfth level of the thoracic vertebrae. It is found to terminate in the splenic hilum. It is also traced to be in close relationship with splenophrenic ligament. The anterior side of the tail is closely related to splenic flexure of the alimentary colon. The tail is very prone to damages during the surgical removal of the pancreas.
Portal vein and portal artery facilities the blood circulation of the pancreas and thus are part of pancreas anatomy in general.
