Flashcards in Stuff I Can't Remember Deck (16):
1

What is an external supravesicular hernia?

Just medial to a direct hernia. At risk of cutting iliohypogastric nerve

2

Where do you anesthetize the scrotum?

Ilioinguinal for anterolateral and
pudendal for inferiorposterior

3

Know the ligaments of:
Liver (4)
Stomach
Spleen

And the arteries and veins that run through some of them.

Liver: (Last 2 part of the lesser omentum
Falciform
Hepatogastric --> Left gastric artery
Hepatoduodenal --> Contains triad (portal vein, hepatic artery, biliary duct)
Coronary ligament --> limits the lesser space's superior recess

Stomach: (all part of the greater omentum)
Gastropyloric
Gastrocolic --> gastroepiploic artery
Hepatogastric
Gastrosplenic -> Short gastric artery; left gastroepiploic artery

Splenorenal ligament --> Splenic artery and vein

4

What organs are in the supracolic compartment?

Infracolic?

What splits the infracolic into righ tand left?

stomach spleen liver

Everything else

Mesentary of small intestine

5

Esophagus and Stomach Histology

Esophagus
Mucosa:
Stratified squamous
Lamina propria has cardiac esophageal glands
Muscularis mucosae present only in lower segment
Submucosa:
Submucosal glands
Submucosal venous plexus drain into portal system
Increase pressure causes esophageal varices
Muscularis externa:
upper=skeletal muscle
middle=skeletal and smooth
Lower=smooth
serosa/adventitia:
Esophagus is only part of digestive system that does not have mesothelium on it’s serosa layer - has adipose instead

Stomach
Mucosa:
Secretory simple columnar epithelium
Lamina propria
Contains Cardiac, gastric, pyloric glands (gastric pits)
Muscularis mucosa facilitates gastric gland secretions
Submucosa:
Dense irregular CT
arteries/veins
NO GLANDS (will help ID the stomach on a slide)
Muscularis externa:
3 layers instead of 2
Circular layer thicker in pyloric region
Serosa:
Loose CT with blood vessels

6

What is Ménétrier’s disease?

Autoimmune gastritis?

Achlorhydia?

Pernicious anemia?

Helicobacter Pylori?

Men disease: TGF-a is low, and causes hypergenesis of mucous cells.

Autoimmune gastritis: Abs eat H/K+ ATPase = no parietal cells to make HCL.

Achlorhydria = Decrease in HCL. Caused by top 2

Pernicious anemia = RBCs made by intrinsic factor made by parietal cells. if gastritis, then no parietal cells = no RBCs = anemia

Helicobacter pylori = Makes a crap ton of ammonia

7

Duodenum parts and important stuff about them, also Vertebral location?
Part 1
Part 2
Part 3
Part 4

Part 1: L1
- hepatoduodenal ligament with hepatic triad.
- Location for duodenal ulcers

Part 2: L1-L3
- Bile enters here via duodenal papilla

Part 3: L3
- Crosses SMA
- Nutcracker Syndrome

Part 4: L3 - L2
- Held by ligametn of duodenum

8

The jejunum and ileum have similar arteries and ligaments attached to them. What are they?

Arteries:
SMA --> Jejunum and ileal arteries --> arterial arcades --> vasa recta
Ligaments:
THE mesentary ligament
Holds: SMA, lymph node, fat, autonomic nerve.
Crosses:
3rd and 4th duodenum
Aorta
IVC
R Ureter
R Psoas Major
R Gonadal vessels

9

Diverticulosis?
Vovlulus of sigmoid colon?
Esophagesal varices?
Pyrosis?
Displaced stomach?
Pylorospasm?
PYloric Stenosis?

Diverticulosis: little pockets
Volvulus: Colon gets twisted
Pyrosis: Heartburn. Hiatal hernias
Displaced stomach by pancreas enlargement
Pylorospasm: stomach muscles can't relax
Pylroic Stenosis: Pylorus is hard, elongated, and narrow. hard to get food through
Carcinoma: Have to cut out everything. Whole spleen, pancreas.
