Case 3 SBA Flashcards
Divisions of the peritoneal cavity
Greater and lesser sac
Greater sac of peritoneal cavity
Starts at diaphragm and descends into pelvic cavity. Is not contained by the reflections
Lesser sac of peritoneal cavity
Lies behind stomach and liver, contained by reflections
Lesser omentum
Connects liver to curvature of the stomach
Medial part of lesser omentum
Hepatogastric ligament
Lateral part of lesser omentum
Hepatoduodenal ligament
Greater omentum
Connects greater curvature of stomach to transverse colon
The mesentery
Anchors small intestine to abdominal wall
Other examples of mesenteries
Mesocolon, sigmoid mesocolon, mesoappendix
Lienorenal ligament
Connects spleen and kidney
Omentum definition
reflection between two organs
Mesentery definition
reflection between organ and posterior abdominal wall
Retroperitoneal organs
Only covered on anterior surface by peritoneum. SADPUCKER (suprarenal glands, aorta, duodenum, pancreas, ureters, colon, kidneys, oesophagus, rectum)
Supra-colic organs
Stomach, liver, gallbladder, spleen
Infra-colic organs
Small intestine, transverse colon, sigmoid colon
Falciform ligament of liver
Attaches to anterior abdominal wall. Becomes coronary ligaments.
Coronary ligaments of liver
Attach liver to diaphragm, meet and form triangular ligament
Main muscles of the posterior abdominal wall
Quadratus lumborum, psoas, ilacus
Sections of the male urethra
pre-prostatic, prostatic, membranous, and spongy
Male vs female urethra length
20cm vs 5cm
Kidney drainage route
papilla → minor calyx → major calyx → renal pelvis → ureter
Which kidney is the most inferior?
Right
What crosses the left renal vein anteriorly?
Superior mesenteric
What connects the supra and infra-colic compartments of the greater sac?
Paracolic gutters
Clinical implications of paracolic gutters
More common to have infection on right side that can spread upwards towards the right subphrenic space (between diaphragm and liver)
