02a: Anatomy Flashcards
Where does the foregut end and midgut begin?
Mid-duodenum
Liver, gallbladder, and spleen are considered part of (fore/mid/hind)-gut. Arterial supply to this area is primarily from (X) and venous drainage primarily via (Y).
Foregut;
X = celiac trunk Y = splenic and gastric veins
T/F: the entire colon (ascending, transverse, descending) is considered part of hindgut.
False - considered midgut up to middle of transverse colon
Arterial supply to midgut is primarily via (X) artery and drainage via (Y) vein.
X = Y = superior mesenteric
Arterial supply to hindgut is primarily via (X) artery and drainage via (Y) vein.
X = Y = inferior mesenteric
Venous drainage of (X) portions of GI tract drain to liver via (Y).
X = ALL Y = hepatic portal system (via hepatic portal vein)
List common branches off celiac trunk.
- Splenic a.
- L. Gastric a.
- Common hepatic a.
Which arteries supply small curvature of stomach? And large curvature?
Small: L and R gastric
Large: L and R gastro-omental; AND short gastric aa
Scenic artery supplies which areas of foregut? Via which branches?
- Greater curvature and posterior wall of stomach (L gastro-omental, posterior and short gastric aa)
- Spleen (Splenic)
- Pancreas (dorsal pancreatic a)
(SMA/IMA) and associated veins/branches are within the mesentery.
Both
Marginal artery of Drummond is important because it connects (X). It’s located in which portion of the (fore/mid/hind)-gut?
X = SMA and IMA
Junction/transition between transverse and descending colon
Portocaval anastamoses may occur in patients with (X) condition. List the three ways these can present.
X = portal hypertension
- Caput medusae
- Esophageal varices
- Internal hemorrhoid
List the primary tributaries to the portal vein.
Splenic, SMV, IMV
All blood entering liver will enter through (X) squad, composed of (Y) structures.
X = portal triad
Y = hepatic a proper, portal v, bile duct
The hepatoduodenal ligament is home to which structures?
Portal triad! (Hepatic a proper, portal v, bile duct)
