Mesenteries And Abdominal Foregut Organs Flashcards
what peritoneum lines the inner surface of abd wall
parietal peritoneum
continuous with visceral peritoneum around organs
CAVITY: make fluid, lower friction of organs, resist infection, mobilize WBCs
2 parts of peritoneal cavity
Greater Sac Lesser Sac (omental bursa)
Mesentary
double layer of peritoneum
attach to interaperitoneal organs
A, V, L travel through it
A LOT OF FAT inside it
regional mesenteries
Peritoneal Ligaments
connect two organs or an organ to the abd wall
Greater Sac vs Lesser Sac
Greater Sac is anterior to lesser sac
Lesser Omentum
A peritoneal Lig of (Heptaoduodenal lig and Hepatogastric Lig)
connects liver to stomach and liver to duodenum (1st part)
Greater Omentum
A peritoneal Lig of (Gastrocolic lig, Gastrophrenic lig, gastrosplenic lig)
Drappes over anterior surface of intestines
connects greater cruve of stomach, duodenum, Tr Colon, to abd wall, spleen, and diaphragm
Epiploic Foramen
Opening connection greater and lesser sacs
ANT : hepatoduedental lig
POST : 1st part of duodenum
SUP : Peritoneal reflection from liver to IVC
INF : peritoneum covering IVC
Stomach loaction right and left
left: T10-T11
right: L1
Esophagus hiatus
T10
Esophagus enter stomach at
cardiac orifice T11
Cardiac notch separates esophagus from stomach
Hiatal Hernia
protrusion of stomach into mediastinum through the esophageal hiatus
2 types sliding and para-esophageal
Para-esophageal Hiatal Hernia
Cardia in normal place
fundus goes through the esophageal hiatus
NO REGURGITATION
Sliding Hiatal Hernia
Cardia and some fundus out from esophageal hiatus
REGURGITATION
Spleen location and ligaments
T9 - T11 ULQ (left hypochondriac region)
Gastrosplenic Lig
Splenorenal Lig
Duodenum 4 parts
PART 1
PART 1 : SUPERIOR
interaperitoneal, sup and right attached to hepatoduedenal ligament
Duodenum 4 parts
PART 2
PART 2: DESCENDING
retroperitoneal, has opening of hepatopancreatic duct
(bile duct + pancreatic duct)
1. Minor Duodenal Papilla - accessory pancreatic duct
2. Major Duodenal Papilla - hepatopancreatic duct
Duodenum 4 parts
PART 3
PART 3 : HORIZONTAL
retroperitoneal, crossed by superior mesenteric A and V
Duodenum 4 parts
PART 4
PART 4: ASCENDING
retroperitoneal, joins to jejunum with the Suspensory Ligament (Ligament of Treitz)
Foregut innervation
SYMPATHETIC
T5- T9 greater splanchnic Nerves from thorax—-> Celiac ganglion
