What is the tail of the pancreas?

The narrow, leftmost portion of the pancreas extending from its body toward the spleen.

In This Section

1. What is the tail of the pancreas?

The narrow, leftmost portion of the pancreas extending from its body toward the spleen.

2. Which part of the pancreas is continuous with the tail?

The body of the pancreas.

3. What is the general direction of the pancreatic tail?

It extends toward the left and slightly superiorly toward the splenic hilum.

4. Which organ lies immediately adjacent to the distal pancreatic tail?

The spleen.

5. Which part of the spleen is closely related to the pancreatic tail?

The splenic hilum.

6. Which peritoneal ligament commonly contains the pancreatic tail?

The splenorenal ligament, also called the lienorenal ligament.

7. What is the peritoneal relationship of the pancreatic tail?

Unlike most of the pancreas, its distal portion is relatively mobile within the splenorenal ligament.

8. Which two major structures accompany the pancreatic tail within the splenorenal ligament?

The splenic artery and splenic vein.

9. What is the relationship between the splenic artery and the pancreatic tail?

The artery courses along its superior aspect toward the splenic hilum.

10. Where is the splenic vein located relative to the pancreatic tail?

It courses posterior to the pancreatic tail and body.

11. Which kidney is related to the posterior aspect of the pancreatic tail?

The left kidney.

12. Which organ lies anterior to the pancreatic tail, with the lesser sac intervening?

The stomach.

13. Which pancreatic duct extends into the tail to collect exocrine secretions?

The main pancreatic duct, also called the duct of Wirsung.

14. In which direction does pancreatic juice flow through the duct within the tail?

Toward the pancreatic body and head.

15. Which embryological pancreatic bud gives rise to the tail?

The dorsal pancreatic bud.

16. Which endocrine structures are particularly abundant in the pancreatic tail?

The pancreatic islets, also called islets of Langerhans.

17. Which pancreatic endocrine cells secrete insulin?

Beta cells of the pancreatic islets.

18. Which pancreatic endocrine cells secrete glucagon?

Alpha cells of the pancreatic islets.

19. Which exocrine cells are present throughout the pancreatic tail?

Pancreatic acinar cells that produce digestive enzymes.

20. Which artery provides the principal arterial supply to the pancreatic tail?

The splenic artery through its pancreatic branches.

21. Which named arterial branch commonly contributes to the blood supply of the pancreatic tail?

The great pancreatic artery, with variable contributions from other pancreatic branches.

22. Where does venous blood from the pancreatic tail primarily drain?

Into the splenic vein through small pancreatic venous tributaries.

23. Which lymph nodes primarily receive lymph from the pancreatic tail?

Pancreaticosplenic lymph nodes along the splenic vessels.

24. Which autonomic nerve plexus contributes to innervation of the pancreatic tail?

The celiac plexus, with fibers following the splenic artery.

25. Why is the pancreatic tail vulnerable to injury during splenectomy?

Its close proximity to the splenic hilum places it at risk during splenic vessel dissection.

26. What surgical procedure commonly removes the pancreatic tail and part of the body?

Distal pancreatectomy.

27. Why may distal pancreatectomy affect glucose regulation?

Removal of islet-rich pancreatic tissue reduces the available endocrine cell mass.

28. What complication can result from disruption of the main pancreatic duct during tail surgery?

A postoperative pancreatic fistula caused by leakage of pancreatic secretions.

29. Why can pancreatic tail inflammation cause splenic vein thrombosis?

Inflammation may involve the adjacent splenic vein, causing thrombosis and impaired venous drainage.

30. What anatomical relationship makes pancreatic tail tumors difficult to distinguish from splenic hilar masses?

The pancreatic tail lies immediately adjacent to the splenic hilum and splenic vessels.
