Gallbladder, Pancreas and Spleen Flashcards
What three parts can the gallbladder be divided into?
Fundus
Body
Neck
Where is the gall bladder?
Peritoneal
Right hypochondriac region
Between right and quadrate lobes of the liver on inferior aspect
Where in the gallbladder neck is a common location for gallstones to get stuck?
Hartmann’s pouch - a mucosal fold
What is the ampulla of vater?
Where the common bile duct joins the pancreatic duct
What is the major duodenal papilla?
Where the pancreatic duct opens into the duodenum
What regulates the opening of the major duodenal papilla?
Sphincter of Oddi
Arterial supply of the gall bladder?
Coeliac trunk - hepatic artery proper - cystic artery
Venous drainage of the gall bladder?
Cystic vein into the portal vein
Innervation of the gall bladder?
Sympathetic and sensory - celiac plexus
Parasympathetic - vagus nerve
Which branch of the autonomic nervous system causes the gall bladder to contract?
Parasympathetic
Is the pancreas peritoneal or retroperitoneal?
Retroperitoneal except for the tail
Where is the pancreas located?
In the epigastrium and left hypochondrium regions
What are the sections of the pancreas called?
Head - fits in curve of duodenum
Uncinate process - projection arising from lower part of the head
Neck - over lies superior mesenteric vessels
Body - crosses midline of human body, behind the stomach
Tail - near hilum of spleen
What is the tail of the pancreas contained in?
The splenorenal ligament along with splenic vessels
Structure of the exocrine pancreas?
Exocrine compartment is a serous gland Made up of berry-like cells - acini Connected by intercalated ducts These drain into interlobular ducts Into the pancreatic duct which runs the length of the pancreas
Arterial supply of pancreas?
Pancreatic branches of splenic artery
Head supplied by:
- gastroduodenal - superior pancreatic duodenal artery
- SMA - inferior pancreatic duodenal artery
Venous drainage of the pancreas?
Body and neck drain into the splenic vein
Head drains into superior mesenteric vein and portal vein
Where is the spleen located?
Upper left quadrant
Left hypochondrium
Rests on left colic flexure
What is the spleen covered in?
Visceral peritoneum
Except for at the splenic hilum
What enters and leaves the spleen at the splenic hilum?
Splenic branches of splenic artery and vein
What is anterior, posterior and medial to the spleen
Anterior - stomach and gastrosplenic ligament
Posterior - left part of diaphragm
Medial - left kidney and splenorenal ligament
Arterial supply of the spleen?
Splenic artery
Describe the route of the splenic artery
Tortuous route
Posterior to omental bursa, anteriorly to left kidney, along superior border of pancreas
Between layers of splenorenal ligament, divides into 5 or more branches which enter the hilum, supplying different vascular segments
Venous drainage of the spleen?
Splenic vein
