Muscular sphincter of esophagus

A

Doesn’t exist! The diaphragm provides the muscular tone to prevent reflux of contents of stomach

Q

Portal-Systemic Anastomoses

A

Area where veins can either drain to hepatic portal system or systemic return. Usually areas like this are affected by portal hypertension

Q

Blood supply to stomach

A

Left gastric artery supplies lesser curvature, short gastric artery from splenic artery supplies fundus, left gastro-omental artery from splenic artery supplies greater curvature, right gastro-omental artery from common hepatic artery supplies greater curvature as well

Q

Venous drainage of stomach

A

Left gastro-omental vein drains to splenic vein and then to portal vein. Right gastro-omental vein drains to superior mesenteric vein and then portal vein. left and right gastric veins follow left and right gastric arteries to drain directly into portal vein

16
Q

Falciform ligament

A

divides liver into right and left lobes anteriorly.

17
Q

Ligamentum venosum

A

shunt between the caudate and left lobe

18
Q

Portal triad

A

Passes through porta hepatis. Contains common bile duct, hepatic artery, and hepatic portal vein.

19
Q

Blood supply of liver

A

Common hepatic artery from celiac trunk. Superior branch of common hepatic artery forms proper hepatic artery which goes to liver and gallbladder

20
Q

Proper hepatic artery

A

Splits from common hepatic artery from celiac trunk. Proper hepatic artery splits into hepatic arteries that supply liver

21
Q

Portal vein

A

receives blood from DIGESTIVE ORGANS. If it’s not a digestive organ, it’s blood probably isn’t going to the liver

22
Q

What type of blood does the liver receive from the portal vein

A

Poorly oxygenated but blood high in nutrients

23
Q

Venous drainage of liver

A

Portal vein, central veins, 3 hepatic veins, then to IVC

24
Q

Biliary Tree

A

bile produced by hepatocytes, exits porta hepatis via bile ducts, forms left and right hepatic ducts, after cystic duct merges this becomes the common bile duct. Common bile duct combines with pancreatic duct at hepatopancreatic ampulla.

25
Q

Major duodenal papilla

A

Entrance into duodenum from common bile duct at hepatopancreatic ampulla

26
Q

Blood supply of gallbladder

A

cystic artery from right hepatic artery

27
Q

Cystohepatic Triangle (of Calot)

A

Contains cystic artery and Lund’s node

28
Q

Borders of cystohepatic triangle

A

cystic duct, common hepatic duct, inferior margin of liver

29
Q

What condition causes enlargement of Lund’s node

A

cholecystitis

30
Q

Location of structures in portal triad

A

Posteriorly: hepatic portal vein, right side: bile duct, left side: hepatic artery

31
Q

parasympathetic innervation of foregut and midgut

A

Vagus nerve

32
Q

Parasympathetic innervation of hindgut

A

pelvic splanchnic nerves from S2, 3, and 4 (preganglionic)

33
Q

Sympathetic innervation of foregut

A

thoracic splanchnic nerve (greater splanchnic nerve)–> celiac ganglion

34
Q

Sympathetic innervation of midgut

A

thoracic splanchnic nerve (lesser splanchnic nerve)–> superior mesenteric ganglion

35
Q

Sympathetic innervation of hindgut

A

lumbar splanchnic nerve–> inferior mesenteric ganglion

36
Q

Autonomic plexus

A

blending of postganglionic sympathetic fibers and preganglionic parasympathetic fibers
