 San Jacenal, Professor, Department Chair. Right supranial gland is like a pyramid. The left supranial gland is like a cocked French hat. This is the right kidney, upper bone and related to the upper bone of the right kidney is the right supranial gland. And separating the kidney from the supranial gland, there is a facial septum. The same fascia is also attached to the under surface of the diaphragm. That's why when there's a nephroptosis, that is a kidney descent sound, the supranial gland does not descend down because it remains attached to the under surface of the diaphragm. On the left side, we can see that the supranial gland is clearly demarcated from the kidney by a clear fascia and it is resting on top of the left renal vein. Right supranial gland, apart from being located in the upper bone of the right kidney, is also closely related to the inferior vena keva. And here it also forms the posterior boundary of the epiploid forano-winslow. The epiploid forano-winslow, as we know, is an opening to the lesser sac which is bounded by the structures of the extrampatic portal tract anteriorly by the liver superiorly, the first part of the diodenum inferiorly and by the inferior vena keva and the right supranial gland posteriorly. And all these things are clearly seen in these pictures. The left supranial gland is closely related to the left renal vein and it is lying on top of the left renal vein. Under this location, the left supranial gland forms part of the bed of the stomach. Each supranial gland gets numerous superior, middle and inferior supranial arteries. The superior comes from the inferior phrenic arteries, the middle comes from the abdominal aorta and the inferior comes from the renal artery. Right supranial gland drains into the inferior vena keva where the left supranial gland drains into the left renal vein and it also communicates with the left inferior phrenic vein. That's all for now. Thank you very much for watching. If you have any questions or comments, put them in the comment section below. Have a nice day. Dr. Sanjay Sanyal signing out.
