Question 2

Answer 2

Question 3

Answer 3

ventral mesentery

Question 4

What’s inside the mesentery?

Answer 4

vessels, nerves, lymphatics

Question 5

The celiac artery divides into…

Answer 5

splenic (givess of short gastric arteries and let gastro-omental artery, which anastomoses with the right gastro-omental artery),

left gastric,

common hepatic (goes to liver, gall bladder, lesser curvature of the stomach, greater curvature of the stomach, head and neck of the pancreas, and proximal part of the duodenum

Question 6

A pt undergoes a cholecystectomy, during which the arterial supply to the gallbladder must be ligated. Within which peritoneal structure is this arterial supply most likely to be found?

Answer 6

Hepatoduodenal ligament.

= the portion of the lesser omentum that connects the liver to the first part of hte duodenum. Within this are the proper hepatic artery and its branches, the common bile duct and its branches, and the portal vein.

Question 7

falciform ligament

Answer 7

mesentery that connects the liver to the anterior abdominal wall. Within the free edge of this is the round ligament of the liver, the adult remnant of the umbilical vein.

Question 8

Gastrocolic ligament

Answer 8

the portion of the greater omentum between the greater curvature of hte stomach and the transverse colon. Contains the gastroepiploic (gastro-omental) vessels.

Question 9

Gastrohepatic ligament

Answer 9

portion of the lesser omentum between the liver and the lesser curvature of the stomach. The right and left gastric vessels are wtihin it along the lesser curvature of the stomach.

Question 10

Splenorenal ligament

Answer 10

mesentery that connects the spleen to the posterior abdominal wall. The splenic artery and splenic vein are within the splenorenal ligament, along with the tail of the pancreas

Question 11

Above vs Below the pectinate line

Answer 11

Above: Visceral (ANS) sensory innervation, portal venous drainage, drain to iliac lymph nodes, internal hemorrhoids (painless), endoderm

Below: somatic sensory innervation, caval venous drainage, drain to superficial inguinal nodes, external hemorrhoids (painful), ectoderm
