the gallbladder

which region is the gallbladder in?

right hypochondrial region

where is the gallbladder in relation to the liver?

inferior surface of the right lobe

what are the 3 parts of the gall bladder?

- fundus

- body

- neck

what is the fundus?

rounded distal portion of gallbladder

what is the body?

the largest part of the gallbladder

what is the neck?

- where the gallbladder becomes continuous with the cystic duct

- leads to biliary tree

what is located in the neck of the gallbladder?

mucosal fold called Hartmann's Pouch

what is the biliary tree?

a series of gastrointestinal ducts which allows newly synthesised bile from the liver to be concentrated and stored in the gall bladder

where is bile secreted from and where does it go?

- it is secreted from hepatocytes and drains from both lobes of the liver via canniculi, intralobular duct and collecting ducts into the left and right hepatic ducts

- these form the common hepatic duct

- the common hepatic duct descends to join the cystic duct which is called the common bile duct

- the common bile duct descends to join the main pancreatic duct forming the hepatopanceatic ampulla (or ampulla of Vater) which empties into the major duodenal papilla

which arteries supply the gallbladder?

the cystic artery - branch of the right hepatic artery - from common hepatic artery - from coeliac trunk

which veins drain the gallbladder?

which nerves supply the gallbladder?

- sympathetic and sensory fibres from the coeliac plexus

although it is intraperitoneal it has an adventitia

what other intraperitoneal structure has an adventitia instead of a serosa?

bare area of the liver

what does the hepatobiliary/cystohepatic/CALOTS triangle borders consist of?

inferiorly - cystic duct

medially - hepatic duct

superiorly - inferior surface of liver

what else is found inside the hepatobiliary/cystohepatic triangle?

cystic artery

what 2 structures are joined in the hepatobiliary/cystohepatic triangle?

cystic duct and cystic artery

what is calot's triangle bordered by?

inferiorly - cystic duct

medially - common hepatic duct
