Flashcards in Abdominal Viscera Deck (31):
0

Foregut Organs

Esophagus, stomach, upper duodenum, pancreas, gall bladder, liver

*All supplied by the celiac trunk

1

Midgut Organs

Lower duodenum, jejunum, ileum, cecum, appendix, ascending colon, proximal 2/3 of transverse colon

*Supplied by the superior mesenteric artery

2

Hindgut Organs

distal 1/3 of transverse colon, descending colon, sigmoid colon, superior rectum

*Supplied by the inferior mesenteric artery

3

Entry point of esophagus into abdominal cavity

T10

4

Stomach regions

1. Cardia

2. Fundus-filled w/ air; radiological landmark

3. Body

4. Pylorus- includes angular notch, antrum, canal, and sphincter

*Intraperitoneal

5

Hepatopancreatic Ampulla of Vater

Receives the common bile duct and main pancreatic ducts to enter the duodenum; enters at the major duodenal papilla of Vater

6

Major Duodenal Papilla of VAter

Marks the jnxn b/w the foregut and midgut

7

Jejunum

Has a thick diameter

Long, few vasa recta

Large windows

Little assoc. fat

8

Ileum

Small, thin wals

Many vasa recta

Numerous, short windows

Few, small plicae circulares

Covered in fat

9

Retroperitoneal parts of the colon

Ascending and descending

*Everything else is intraperitoneal including the appendix

10

Teniae coli

Longitudinal muscle bands along the center of the colon

11

Haustra

Sacculations of colon produced by the colon

12

Epiploic appendices

Peritoneum-covered pouches of fat along the teniae

13

Spleen

Located in the left hypochondral region, is intraperitoneal, posterior to the stomach, and medial to the left kidney

*Connected to the gastrosplenic ligament and the splenorenal ligament

14

Pancreas

Main pancreatic duct drains into the hepatopancreatic ampulla and the accessory pancreatic duct drains the small head into the minor duodenal papilla

*Retroperitoneal structure

15

Liver

Intraperitoneal organ found in the right hypochondral and epigastric egions

*Attached to peritoneum by the coronary and faliciform ligments (contains ligamentum teres)

16

Obliterated Umbilical Vein

Ligamentum teres hepatis; part of the faliciform ligament connecting the liver to the anterior abdominal wall

17

Obliterated ductus venosus

Ligamentum venosum; connected the umbilical vein to the IVC

18

Hepatoduodenal ligament

Connects the duodenum and liver in the lesser omentum and contains the portal triad

19

Gall Bladder

Located @ the 9th costal cartilage and lateral border of the R. rectus abdominus; intraperitoneal structure

20

Cystohepatic triangle of Calot

Formed by the visceral surface of the liver(superiorly), the cystic duct (inferiorly), and the common hepatic duct(medially)

*Contains the cystic artery; enlarged during cholecystitis

21

Drainage of cystic-biliary ducts

Bile produced by the liver travels down thru the R/L hepatic duct, thru the common bile duct, and finally thru the cystic duct to be stored in the gall bladder

=>Gall bladder empties into the cystic duct and drains to the bile duct which meets up w/ the main pancreatic duct to form the hepatopancreatic ampulla of Vater

22

Fractured ribs

Can lead to a ruptured spleen

23

Volvulus

Abnormal twisting of the intestines that can cause intestinal obstruction and interrupted blood supply

24

Transpyloric Plane

Lies b/w the xiphoid process and umbilicus @ Level L1

*Passes thru the pylorus of the stomach, duodenojejunal jnxn, hila of the kidneys, and tips of the 9th costal cartilage

25

Suspensory Muscle of the Duodenum

Secures duodenum to the diaphragm; maintains the C-shape of the duodenum

26

Vermiform Appendix

Is usually retrocecal (behind the colon); base lies deep to McBurney's point
*Intraperitoneal

27

Illeal Diverticulum of Meckel

Congenital remnant of the yolk sac that can be a site of inflammation/infxn

Rule of 2s: 2% have it
Within 2 feet of iliocecal valve
~2 inches in length
Presents within first 2 years
Can contain 2 tissue types (gastric/pancreatic)

28

Unicinate Process of Pancreas

Only part superior to the superior mesenteric vessels; can easily compress then if a mass is present

29

Obstructive jaundice

Blockage of the bile ducts causing jaundice

*Often how pancreatic cancers are detected

30

Situs inversus

Rare left-right flipping of the orientation of the abdominal viscera
