Study Notes
Anatomical Structures and Regions
- The left hypochondriac region does not contain the appendix.
- The lesser sac (omental bursa) is positioned behind the stomach and the lesser omentum.
Vascular Supply
- The stomach receives arterial supply primarily from the gastric and gastroepiploic arteries.
- The celiac trunk is the main arterial source for structures derived from the foregut.
- The artery supplying the ascending colon is the ileocolic artery from the superior mesenteric artery.
- The arterial supply for the duodenum includes branches from the celiac trunk and the superior mesenteric artery.
Ligaments and Connections
- The splenorenal ligament connects the spleen to the greater curvature of the stomach.
- The hepatogastric ligament connects the liver to the stomach.
- The gastrocolic ligament forms the anterior boundary of the omental bursa and contains the right and left gastroepiploic arteries.
- The lesser omentum consists of two parts: hepatogastric and hepatoduodenal ligaments.
Liver and Function
- The liver's primary function is detoxification, protein synthesis, and production of biochemicals necessary for digestion.
- 80% of the liver's blood supply comes from the portal vein, while arterial supply comes from the hepatic artery.
Sympathetic and Parasympathetic Innervation
- The greater thoracic splanchnic nerve provides preganglionic sympathetic innervation to foregut structures.
- Preganglionic sympathetic fibers synapse in the celiac ganglion.
- The vagus nerve carries preganglionic parasympathetic innervation to foregut structures.
- The sympathetic innervation of the midgut originates from the superior mesenteric ganglion.
- Lumbar splanchnic nerves supply sympathetic innervation to the hindgut.
Peritoneum and Cavity
- The peritoneum consists of parietal and visceral layers.
- Ascites, an accumulation of fluid in the peritoneal cavity, can lead to infection or abdominal compartment syndrome if untreated.
- Surgical puncture for ascites drainage is typically done in the lower left quadrant.
Organs and Anatomical Classifications
- Examples of intraperitoneal organs include the stomach, spleen, and liver.
- Retroperitoneal organs include the kidneys, pancreas, and aorta.
- The structures found in the portal triad are the hepatic artery, portal vein, and bile duct.
- The common bile duct is the combination of the cystic duct and the common hepatic duct.
Lymphatics and Venous Drainage
- The stomach's venous drainage primarily follows the same pattern as its arterial supply, draining into the portal vein.
- Lymphatic drainage of the stomach is not supported by the inferior mesenteric nodes.
Anastomoses and Clinical Aspects
- Four main naturally occurring portal-caval anastomoses include connections at the esophagus, umbilicus, rectum, and abdominal wall.
- Ascites result from liver cirrhosis, heart failure, or cancer.
Notable Exceptions
- The common bile duct is not solely part of one anatomical region; it serves multiple functions in the biliary system.
- The appendix is located in the right lower quadrant, with its surface projection referred to as McBurney's point.
