Canine Vasculature and Abdominal Nervous System Flashcards
Parent to Abdominal Aorta
- Descending Aorta
Main Branches of the Abdominal Aorta
- Celiac a.
- Cranial mesenteric a.
- Caudal mesenteric a.
Lumbar arteries
- Paired
- Means L & R
- Leave dorsal surface of the abdominal aorta
- Extend dorsally towards the vertebral column
- Terminate as a dorsal and spinal branch (can’t see them on specimen)
Dorsal branches of the lumbar arteries
- Supply the muscle and skin above the lumbar vertebrae
Celiac a.
- Main branch off of the Abdominal Aorta
- Arises between the crura of the diaphragm
- Seen under the celiacomesenteric ganglia and plexus
- 3 Branches:
- Hepatic a.
- Left gastric a.
- Splenic a.
- 3 Branches:
Hepatic a.
- 1st branch off of Celiac a.
- Courses cranially in cranial border of mesoduodenum
- Passes into liver in hepatoduodenal ligament
- Gives off 1-5 branches that supply the liver
- Cystic artery from the last hepatic branch supplies gallbladder
- Terminates as:
- Right gastric a.
- Gastroduodenal a.
Artery that supplies the gallbladder
- Cystic a. (last branch off of the hepatic a. )
Right Gastric a.
- Branch off of Hepatic a.
- Extends from the pylorus to the cardia
- Supplies the lesser curvature of the stomach
- Anastomeses with the left gastric a.
Gastroduodenal a.
- Branch off of the hepatic a.
- Supplies the pylorus (not much of anything else)
- Terminates as:
- Right gastroepiploic a.
- Cranial pancreaticoduodenal a.
Right Gastroepiploic a.
- Branch off of the gastroduodenal a.
- Supplies the greater omentum
- Supplies greater curvature of the stomach
- Anastomoses with L. gastroepiploic a.
Parent vessel of Right Gastric a.
- Hepatic a.
Blood Supply to the Lesser Curvature of the Stomach
- Right gastric a.
- Left gastric a.
Parent Vesel to the Gastroduodenal a.
- Hepatic a.
Parent Vessel to R. Gastroepiploic a.
- Gastroduodenal a.
Cranial pancreaticoduodenal a.
- Branch of the gastroduodenal a.
- Around the mesenteric border of the descending duodenum
- Supplies the R. lobe of the pancreas and descending duodenum
Parent Vessel to Cranial pancreaticoduodenal a.
- Gastroduodenal a.
Blood Supply to the R. Lobe of the Pancreas
- Cranial pancreaticoduodenal a.
Blood Supply to the Descending Duodenum
- Cranial pancreaticoduodenal a.
Left gastric a.
- Runs the length of the lesser curvature of the stomach to the cardia
- Supplies the lesser curvature of the stomach and the cardia
Blood Supply to the Cardia
- Left gastric a.
Parent Vessel to the Left Gastric a.
- Celiac a.
Parent Vessel to the Splenic a.
- Celiac a.
Splenic a.
- Crosses the dorsal surface of the L. lobe of the pancreas
- Supplies the L. lobe of the pancreas
- Divides into dorsal and ventral splenic branches
- Dorsal Branch
- Short gastric aa.
- Supply the L. side of the greater curvature of the stomach
- L. gastroepiploic a.
- Supplies the greater curvature of the stomafh
- Anastamoeses with R. gastroepiploic a. at the pyloric end
- Short gastric aa.
- Ventral Branch
- Supplies the spleen
- May also give rise to L. gastroepiploic a.
- Dorsal Branch
Parent Vessel to the L. Gastroepiploic a.
- Dorsal branch of the splenic a.
