Q

What happens when there is a union of a branch from the celiac trunk and Superior Mesenteric A.?

A

This marks the transition to the Midgut

The Superior and Inferior Pancreaticoduodenal come from the SMA and Celiac trunk, after this union we transition to the midgut

28
Q

What innervates the Duodenum?

A

Vagus
- Secretomotor to the duodenal mucosa and motor to the duodenal musculature

Greater and Lesser Splanchnic

29
Q

Where does the duodenal refer pain to?

A

Epigastrium

30
Q

32
Q

Where is the jejunum located? What artery supplies it?

A

What is the Gallbladder function?

A

Store bile produced by liver

50
Q

How does bile make it from the Liver to the Gallbladder?

A

From the liver it goes to the L/R Hepatic duct -> Common Hepatic Duct -> Common Bile Duct -> Reaches the sphincter of the bile duct then rebounds back up -> Cystic duct -> Gallbladder
