Anatomy Flashcards
(23 cards)
covers abdominal viscera; vasculature & nerve supply from organ it covers
Visceral peritoneum
lines abdominal cavity wall; vasculature & nerve supply same as the region it covers
Parietal peritoneum
Parietal peritoneum sensitive to + where does pain go?
pressure, pain, heat, cold, and laceration
pain well localized
Visceral peritoneum sensitive + pain
insensitive to touch, heat, cold, and laceration
sensitive to stretch and chemical irritation
pain referred to region the organ belongs to
peritoneal formations
- mesentery
- omentum
- peritoneal ligament
mesentery
connects the intraperitoneal organs to the abdominal walls
peritoneal ligament
connects an organ to another organ
foregut organs
Biliary Ducts Duodenum Esophagus Liver Stomach
foregut pain and blood supply
pain referred to epigastrium
supplied by celiac trunk
midgut organs
Cecum Appendix Small intestine (duodenum) Proximal transverse colon Ascending colon
midgut pain and blood supply
pain referred to periumbilical
supplied by superior mesenteric artery
hindgut organs
Distal transverse colon
Descending colon
Rectum
Sigmoid
hindgut pain and blood supply
referred to hypogastrium
inferior mesenteric artery
esophagus muscle control
proximal 1/3 voluntary striated
middle mixture
distal 1/3 smooth muscle
esophageal hiatus
where the esophagus prices the diapraghm
T10
peritoneal cavity by gender
closed in males open in women
hepatopancreatic ampulla
ampulla of vater
where common bile and pancreatic ducts join to enter duodenum
vasculature of duodenum
celiac trunk (proximal to ampulla of vater)
superior mesenteric artery (distal to ampulla of vater)
venous drainage of digestive tract
portal system
location of the appendix
MC retrocecal
hepatic blood supply
dual supply hepatic artery and portal system
Hepatic artery:
branch off celiac trunk
Supplies 20-25% of blood to liver, mostly to hepatic ducts (non-parenchymal)
Hepatic Portal System:
hepatic portal vein delivers blood from GI tract to the liver for filtration and provides nutrition and oxygen
