Flashcards in Peritoneum, Peritoneal Cavity and Mesenteries - Thomas Deck (29)
Branches of the celiac trunk and the part of gut it is responsible for
Branches of superior mesenteric and the part of gut it is responsible for
Branches of inferior mesenteric and the part of gut it is responsible for
Peritoneum - 2 layers and pain fibers
1. Parietal - lines body wall - abundant pain fibers
2. Visceral - covers viscera - lacks pain fibers
Sensitive to stretching and chemical irritation
Insensitive to touch, heat, cold, laceration
Is the pain from visceral peritoneum localized?
-crampy, colicky pain
Covered on most sides by visceral peritoneum
Suspended from mesentery from body wall
Lie deep to the parietal peritoneum
Covered only on one side by parietal peritoneum
Primarily Retroperitoneal organs
Suprarenal glands (aka adrenals)
Aorta and IVC
Secondarily Retroperitoneal organs
Became retroperitoneal during development
Duodenum (desc, horiz, ascen)
Ascending and descending colon
Attaches the 'free' small intestine to the posterior body wall
Where is the ventral mesentery?
Extends from the respiratory diaphragm to the duodenum
What runs through the dorsal mesentery?
Dorsal aorta and it's 3 branches
What mesenteries are lost during development?
Duodenum, ascending colon, descending colon and cecum
-since no longer suspended from mesentery, considered secondarily retroperitoneal
1. Gastrosplenic ligament
2. Splenorenal ligament
-transmit nerves and vessels
-lack connective tissue
-2 layered sheet of peritoneum that attaches stomach to other viscera
Lesser - from ventral mesogastrium
Greater - from dorsal mesogastrium
Lesser omentum is composed of what 2 ligaments?
3 ligaments of greater omentum
1. Gastrocolic l.
2. Gastrophrenic l.
3. Gastrosplenic l.
What are the 3 ligaments associated with liver?
R and L triangular l
What runs in the falciform ligament?
Ligamentum teres hepatis
-obliterated umbilical vein
Folds of the abdominal walls
Median umbilical fold
-urachus, midline from bladder
Medial umbilical folds (2)
-obliterated umbilical a.
Lateral umbilical folds (2)
-inferior gastic vessels, functional a and v.
Supravesical fossa - supravesical hernias
Medial inguinal fossa - direct inguinal hernias
Lateral inguinal fossa - indirect inguinal hernias
Where do supravesical hernias occur?
Where do direct inguinal hernias occur?
Medial inguinal fossa
Where do indirect inguinal hernias occur?
Lateral inguinal fossa
Most of the potential space in abdomen
Can be subdivided into supra colic and infra colic regions by colon and transverse mesocolon
Excess fluid in abdomen
-abscesses may develop
Posterior and inferior to the stomach
Can get fluid that leads to infection
