Flashcards in 2017 Anatomy - Peritoneum, Esophagus, Stomach, Small Intestine, Spleen Deck (28):
1

Which mesentary gives rise to the Greater and which gives rise to the Lesser Omentum?

Dorsal = greater

Ventral = lesser

2

What are the two ligaments of the lesser omentum and where do they run from/to?

Hepatogastic: Stomach - Liver (Medial)

Hepatoduodenal: Duodenum -Liver (Lateral)

3

Through what opening do the Greater and Lesser Sacs (Omental Bursa) communicate?

Epiploic Foramen

4

Which vessels run through the Hepatoduodenal ligament?

Hepatic Artery

Hepatic Portal Vein

Bile Duct

5

At what level (aprox.) does the esophagus pierce the diaphagm?

T10

6

Which nerve makes up the Anterior Vagal Trunk (plexus) and which makes up the Posterior?

Left = Anterior

Right = Posterior

7

What is the name of the opening of the stomach into which the esophagus opens, what is the name of the feature which makes the change in epithelium type here?

Cardial Orfice

Z-line

8

What is a disease of the esophagus caused by increase portal hypertension?

Esophageal varices

9

What are the 4 major regions of the stomach?

Cardia

Fundus

Body

Pyloric

10

What are the 4 features of the stomach?

Greater Curvature

Lesser Curvature

Cardial Notch

Angular Incisure

11

What 7 organs are a part of the "bed of the stomach"?

Diaphragm (left dome)

Spleen

Left Kidney

Suprarenal Galnd

Pancreas

Trasverse Mesocolon

Colon

12

What are the ligaments/attachments of the stomach?

Gastrospleic ligament: from greater omentum, connects greater curve to hilum of spleen

Gastrophrenic ligament: from greater omentum, connects greater curve to inferior surface of diaphragm

Gastrocolic ligament: greater omentum, connects greater curve to transverse colon

Hepatogastic ligament: lesser omentum, lesser curve to liver

13

What are the 4 groups of lymph nodes of the stomach and where do they ultimately drain (nodes and duct)?

Gastric Lymph Nodes - cardia and superior stomach

Pancreaticosplenic - posterior stomach along the Splenic Artery

Gastro-Omental - inferior portion of greater curve

Pyloric - around pyloric canal

All drain to Celiac Lymph Nodes and into the Thoracic Duct

14

Understand the basic arterial supply of the stomach?

15

From where does the:

left gastric artery

right gastric artery

right gastro-omental artery

left gastro-omental artery

posterior gastric artery

arise?

Celiac Trunk

Hepatic Artery Proper

Gastroduodenal Artery

Splenic Artery

Splenic Artery

16

What are the 3 segments of the small intestine?

Duodenum

Jejunum

Ilium

17

What is the first portion of the duodenum and some important features?

Superior portion

located right of L1 body

passes anteior to bile duct, gastroduodenal artery, portal vein, and IVC

clincally called the duodenal cap and site of duodenal ulcers

18

What is the second portion of the duodenum and some important features?

Descending portion

extends down right side of L1-L3

contains the Major Duodenal Papilla, entrance of bile duct and pancreatic ducts.

also contains Minor Duodenal Papilla, entrance of accessory pancreatic duct

 

19

 What is the importance of the Major Duodenal Papilla embroylocigally and vascularly?

Marks the fusion of the foregut with the midgut

Proximal to MDP = perfused by Celiac Trunk

Distal to MDP = perfused by Mesenteric Artery (Superior or Inferior)

20

What is the third portion of the duodenum and some important features?

Inferior portion

longest section, runs horizontally across at L3

it crosses the IVC and is crossed by the Superior Mesenteric Artery

21

What is the fourth portion of the duodenum and some important features?

What is the name of the ligament at the end of the duodenum, supporting it?

Ascending Part

passes upward to the left of abdominal aorta

ends at L2 level with duodenojejunal flexure

Suspensory Muscle (ligament) of duodenum (aka Ligament of Treitz)

22

Know the vascular supply of the duodenum

23

Which has a thicker wall, Jejunum or Ilium?

Jejunum

24

Compare the Plicae Circularis of the Jejunum and Ilium?

Larger and more pronounced in Jejunum.

25

How do the Jejunum and Ilium get their arterial supply? Describe the differences in Vasa Recta of the two segments.

via Jejunal/Ilial Arteries which are branches of the Superior Mesenteric Artery

Jejunum has fewer but longer Vasa Recta

Ilium has more/longer Arterial Arcades

26

What is a histological feature unique to the Ilium?

Peyer's Patches

27

Where is the spleen and what organs/features surround it?

Left hypochondriac

anterior - stomach

posterior/lateral - ribs 9-11

medial - left kidney

inferior - left colic flexure

superior - diaphragm

28

What vessels and ligaments attach to the hilum of the spleen?

the Splenic Artery and Vein

Splenorenal ligament - spleen to kidney

Gastrosplenic Ligament - spleen to stomach
