Lecture 23: Abdomen III: Foregut Flashcards
what are the 3 branches of the celiac artery
splenic branch (largest)
- supplies spleen, pancreas and part of stomach
hepatic branch
- supplies liver, gallbladder, pancreas, duodenum
left gastric
- supplies part of stomach, esophagus
branches of the splenic artery
small pancreatic branches
left gastroepiploic (gastromentum)
branches of left gastric artery
esophageal
branches of the hepatic artery
proper hepatic arteries
- cystic
right gastric
gastroduodenal
- cranial pancreaticoduodenal
- right gastroepiploic
what does the splenic artery supply blood to
spleen, pancreas, stomach
what does the hepatic artery supply blood to?
liver, gallbladder, pancreas, duodenum
what does the left gastric artery supply blood to?
stomach and esophagus
where do the vagal trunks travel and what do they do
travel through the esophageal hiatus
deliver preganglionic sympathetic axons to the fore and midgut
what is the function of the major and minor splanchnic nerves
to deliver preganglionic sympathetic axons from the abdomen to the celiac and cranial mesenteric ganglia where synapse will occur
what is the route postganglionic sympathetic axons follow to the organs
celiac–>foregut–>cranial mesentertic–>midgut
what are periarterial plexuses
blood vessels on which both postganglionic sympathetic and parasympathetic axons travel along to be distributed to organs
once through the esophageal hiatus, what does the esophagus join with
the cardia of the stomach
what tissues and cells are required for esophageal transport
stratified squamous epithelial cells (protection)
mucous glands (lubrication)
skeletal and smooth muscle
what is the transitional anatomy that is evident in the esophagogastric junction
epithelium transitions from stratified squamous to simple columnar
what are the functions of the stomach
- food reservoir
- secretes gastric juices
- rhythmic segmentation to
begin the mechanical breakdown of food - forms chyme
- initiates protein digestion
