Ab Cavity 3 Flashcards
greater peritoneal sac
potential space
around stomach and spleen
lesser peritoneal sac
space behind stomach
between posterior body wall and stomach
provides mobility for the stomach
greater omentum made of 3 parts
- gastrocolic lig: connects stomach to transverse colon
- gastrolineal lig: connects spleen to greater curvature
- gastrophrenic lig: connects stomach to diaphragm
lesser omentum made of 2 parts
- hepatoduodenal lig: connects liver to duodenum
- hepatogastric lig: connects liver to stomach
dorsal mesointestine
supports ileum and jejunum
dorsal mesocolon
supports cecum
mesoappendix
supports appendix
transverse mesocolon divides abdominal cavity into
- supracolic compartment
- infracolic compartment
supracolic compartment
stomach, liver, spleen
infracolic compartment
small intestine, ascending colon, descending colon
sigmoid mesocolon
supports sigmoid colon
lienorenal ligament
passes from left kidney to spleen
gastrolienal ligament
passes from stomach to spleen
coronary ligament of liver
peritoneal reflections around bare area of liver
heatorenal ligament of liver
coronary ligament running between peritoneum above right kidney and liver
falciform ligament of liver
remnant of ventral mesentery connecting liver to anterior body wall
part of falciform ligament is the ligamentum teres
aka round ligament
remnant of fetal umbilical vein
layers of digestive tract

muscularis externa layers
inner circular layer
outer longitudinal layer
mucosa layers
muscularis mucosa
lamina propria
epithelium
jejunum characteristics
deep red color, 2-4cm, wall is thick and heavy, great vascularity, long vasa recta, few large loops of arcades, less fat in mesesntery, large and numerous plicae circulares
ileum characteristics
pink color, 2-3cm, wall thin and light, less vascularity, short vasa recta, many short loops of arcades, more fat in mesentery, low and sparse plicae circulares
porta hepatis of liver
transverse fissure where major vessels pass through
portal vein
carries O2 poor, nutrient rich blood from the gut
