?

1. what is the outer layer of the stomach

  • mucosa: gastric glands (releases mucus at cardia, HCl at fundus and gastrin at pylorus) and muscularis mucosae (sm)
  • muscularis externa (oblique, circular and longitudinal) and meistener's plexus
  • submucosa - meistener's plexus
  • serosa
  • submucosa - aubachs plexus
  • muscularis externa (oblique, circular and longitudinal) and aubachs plexus

Other questions in this quiz

2. what is the function of the aubach's plexus

  • controls circular and longitudinal muscle contractions
  • controls oblique, circular and longitudinal muscle contractions
  • controls gland secretions
  • controls gastric folding

3. what is the blood supply to the lesser curvature

  • LEFT: superior mesenteric -> common hepatic a. -> left gastric branch (along lesser curvature). RIGHT: superior mesenteric -> right gastric (along lesser curvature). right and left anastomes
  • LEFT:coeliac trunk -> common hepatic a. -> gastroduodenal a. -> left gastro-omental/gastro-epiploic (along lesser curvature). RIGHT: coeliac trunk -> splenic a. -> right gastro-omental/gastro-epiploic (along lesser curvature). right and left anastomes
  • LEFT: coeliac trunk -> right gastric (along lesser curvature) to midline. RIGHT: coeliac trunk -> right gastric (along lesser curvature). right and left anastomes
  • LEFT: superior mesenteric -> common hepatic a. -> gastroduodenal a. -> left gastro-omental/gastro-epiploic (along lesser curvature). RIGHT: superior mesenteric -> splenic a. -> right gastro-omental/gastro-epiploic (along lesser curvature). right and left anastomes
  • LEFT: coeliac trunk -> left gastric (along lesser curvature). RIGHT: coeliac trunk -> common hepatic a. -> right gastric branch (along lesser curvature). right and left anastomes
  • LEFT: coeliac trunk -> splenic a. -> left gastro-omental/gastro-epiploic (along lesser curvature). RIGHT: coeliac trunk -> common hepatic a. -> gastroduodenal a. -> left gastro-omental/gastro-epiploic (along lesser curvature). right and left anastomes

4. what are the ligaments of the lesser omentum

  • hepatogastric (between lesser curvature of stomach and liver, contains portal triad) and hepatoduodenal (top of duodenum to liver)
  • hepatogastric (between greater curvature of stomach and liver, contains portal triad) and hepatoduodenal (top of duodenum to liver)
  • hepatoduodenal (between lesser curvature of stomach and liver, contains portal triad) and hepatogastric (top of duodenum to liver)
  • hepatogastric (between greater curvature of stomach and liver) and hepatoduodenal (top of duodenum to liver, contains portal triad)
  • hepatogastric (between lesser curvature of stomach and liver) and hepatoduodenal (top of duodenum to liver, contains portal triad)
  • hepatoduodenal (between lesser curvature of stomach and liver) and hepatogastric (top of duodenum to liver, contains portal triad)

5. what's clinically relevant about the lymphatics of the oesophagus

  • they're bidirectional: drains to deep cervical and juxtaoesophageal nodes - important for spread of cancer
  • very complex, so hard to find root of cancer
  • stomach cancer metastasises through the juxtaoesphageal nodes
  • throat cancer metastasises down to juxtaoesphageal nodes
