Anatomy Topic 2 Case 7 Flashcards
The spleen is derived from which germ layer?
- Dorsal mesentery
Which abdominal region is the spleen located in?
- Left hypochondrium
How is the spleen connected to the greater curvature of the stomach?
- Gastrosplenic ligament
How is the spleen connected to the left kidney?
- Splenorenal ligament
Which region of the spleen is not covered by visceral peritoneum?
- Hilum
Outline the arterial supply of the spleen
- Splenic artery
- Branch of coeliac trunk
Outline the pathway taken by the splenic vein
- Passes through the splenorenal ligament
- Joins the superior mesenteric vein
- To form the portal vein
Outline the lymphatic drainage of the spleen
- Pancreaticosplenic nodes
- Drain into coeliac nodes
- Drain into pre-aortic lymph nodes
Outline the innervation of the spleen
- Vasomotor fibres from greater splanchnic nerve
- Via the coeliac plexus
- Which stimulates vasoconstriction
In which abdominal region is the liver located?
- Right hypochondrium
- Epigastric region
- Left hypochondrium
Identify the two recesses of the liver
- Subphrenic recess
- Hepatorenal recess
Identify the two regions of the liver that are not covered by visceral peritoneum
- Fossa for the gall bladder
- Porta hepatis
What is the porta hepatis?
- Point of entry into the liver for the hepatic arteries and portal vein
- Exit point for hepatic ducts
What is the role of the falciform ligament?
- Attachment of liver to anterior abdominal wall
- Separates liver into left and right areas
Identify four additional ligaments associated with the liver
- Hepatogastric ligament
- Hepatoduodenal ligament
- Right and left triangular ligaments (diaphragm)
- Anterior and posterior coronary ligaments
Which lobe is superior, the caudate or quadrate lobe?
- Caudate
‘Caudate lobe is bounded on the left by the [A] and on the right by the [B]’
- [A] Ligamentum teres
- [B] Fossa for the gallbladder
‘Quadrate lobe is bounded on the left by the [A] and on the right by the [B]’
- [A] Ligamentum venosum
- [B] Inferior vena cava
Outline the arterial supply of the liver
- Common hepatic artery
- Gives off a terminal branch known as the hepatic artery proper
- Which divides into right and left hepatic arteries
- At the porta hepatis
Which artery supplies the gall bladder?
- Cystic artery
- Branch of hepatic artery proper
Outline the lymphatic drainage of the liver
- Coeliac nodes
Outline the innervation of the liver
- Coeliac plexus
- Anterior vagus nerve also gives rise to large hepatic branch
Outline the pathway taken by the portal vein
- Enters hepatic sinusoids
- Until it reaches the hepatic veins
- Which returns blood to the inferior vena cava
