Summary of Gallbladder and Liver Anatomy
1. Location of the Gallbladder:
✔️ Located in the posterior inferior margin of the liver.
2. Liver Lobes:
✔️ The liver is divided into 4 lobes:
- Major lobes: Right and Left lobes
- Minor lobes: Quadrate and Caudate lobes
3. Position in the Abdomen:
✔️ The liver is primarily located in the right upper quadrant (RUQ) of the abdomen.
4. Structure Dividing the Liver:
✔️ The falciform ligament divides the liver into left and right lobes.
5. Bile Formation:
✔️ Bile is formed in the liver.
6. Main Function of Bile:
✔️ To break down or emulsify fats.
7. Functions of the Gallbladder:
✔️ Which functions are performed by the gallbladder?
- a. Storage of bile
- b. Concentration of bile
- c. Contraction and release of bile
, - d. All of the above
✔️ d. All of the above.
8. Bile Secretion:
✔️ The liver secretes approximately 800 to 1000 mL of bile per day.
9. Functions of the Liver:
✔️ True: The liver performs more than 100 different functions.
10. Ducts Related to the Liver and Gallbladder:
- ✔️ The duct formed by the union of the left and right hepatic ducts is the common hepatic duct.
- ✔️ The duct that carries bile from the cystic duct to the duodenum is the common bile duct.
11. Gallbladder Dimensions:
✔️ The average adult gallbladder is 7 to 10 cm long and 3 cm wide.
12. Concentration of Bile in the Gallbladder:
✔️ The process that leads to the concentration of bile is hydrolysis.
13. Function of Cholecystokinin:
✔️ A primary function of cholecystokinin is to stimulate the gallbladder to contract.
14. Production of Cholecystokinin:
✔️ Cholecystokinin is produced in the duodenal mucosa.
15. Anatomical Aspect of the Gallbladder:
✔️ The aspect of the gallbladder located most posteriorly within the abdomen is the neck.
, 16. Membranous Folds in the Cystic Duct:
✔️ The primary purpose of the membranous folds is to prevent distention or collapse of the cystic
duct.
- ✔️ The series of mucosal folds in the cystic duct is called the spiral valve.
17. Protrusions and Parts of the Gallbladder:
- ✔️ A protrusion into the duodenum is called the duodenal papilla.
- ✔️ The middle aspect of the gallbladder is referred to as the body.
- ✔️ The duct directly connected to the gallbladder is the cystic duct.
- ✔️ The narrowest portion of the gallbladder is the neck.
- ✔️ The broadest portion of the gallbladder is the fundus.
18. Common Bile Duct and Pancreatic Duct Structures:
✔️ The enlarged chamber in the distal aspect of the common bile duct is the hepatopancreatic
ampulla.
19. Older Terms:
- ✔️ The duct of Wirsung is the older term for the pancreatic duct.
- ✔️ The sphincter of Oddi is the older term for the hepatopancreatic sphincter.
20. Muscle Fibers Adjacent to Duodenal Papilla:
✔️ Hepatopancreatic sphincter describes the circular muscle fibers adjacent to the duodenal papilla.
21. Duct Union Statistic:
✔️ False: In 40% of all individuals, the common bile duct and the pancreatic duct unite before
entering the duodenum.
Which term describes the condition of having gallstones? ✔️Cholelithiasis
"Chole-" is a prefix for terms pertaining to the: ✔️Bile
