Q

falciform ligament

A

extends from the liver to the diaphragm and ventral abdominal wall to the umbilicus

18
Q

vagus nerve

A

carries both sensory and motor axons from and to the viscera

19
Q

dorsal and ventral branches of vagus nerve

A
20
Q

dorsal vagal trunk

A

dorsal branches unite near the diaphragm

21
Q

ventral vagal trunk

A

ventral branches unite caudal to the root of the lung

22
Q

celiac branch

A

of dorsal vagal trunk that passes dorsocaudally and contributes to the formaiton of the celiac and cranial mesenteric plexuses

23
Q

splanchnic nerves

A

contain sympathetic axons that run between the sympathetic trunk and the abdominal ganglia as well as axons of visceral afferent coursing to the spinal cord

24
Q

major splanchnic nerve

A

leaves the sympathetic trunk at the level of the 12th ot 13th thoracic sympathetic ganglion. passes dorsal to the crus of the diaphragm enters the abdominal cavity, and courses to the adrenal and celiacomesenteric ganglia and plexuses

25
Q

minor splanchnic nerves

A

generally 2, leaves the last thoracic and lumbar sympatheric ganglia, supply nerves to the adrenal gland, ganglion, and plexus, and terminate in the celiacomesenteric ganglia and plexus

26
Q

lumbar splanchnic nerves

A

arise from the 2nd to the 5th lumbar sympathetic ganglia

27
Q

celic ganglia

A

lie on the right and left surfaces of the celiac artery close to its origin

28
Q

cranial mesenteric ganglion

A

located caudal to the celiac ganglion on the sides and caudal surface of the cranial mesenteric artery, which is partially encircles

29
Q

celiacomesenteric ganglion and plexus

A
30
Q

caudal mesenteric ganglion

A

located ventral to the aorta around the caudal mesenteric artery

31
Q

caudal mesenteric plexus

A

some nerves leaving the ganglion continue along the artery

32
Q

right and left hypogastric nerves

A

leave the caudal mesenteric ganglion and course caudally near the ureters

33
Q

celiac artery

A

short and arises from the aorta between the cura of the diaphragm - has 3 branches (hepatic, left gastric, splenic)

34
Q

hepatic artery

A
  • first branch to leave the celiac artery
  • courses cranially in the cranial border of the mesoduodenum, which is the caudal boundary of the epiploic foramen
  • passes to the liver in the hepatoduodenal ligament
35
Q

left gastric artery

A

branches form the celiac and runs in the greater omentum to the lesser curvature of the stomach near the cardia and supplies both surfaces of th stomach

36
Q

splenic artery

A

crosses the dorsal surface of the left lobe of the pancreas in the deep leaf of the greater omentum - to which it may supply branches - befcore dividing into dorsal and ventral splenic branches that enter the hilus of the spleen on its visceral surface

37
Q

cranial mesenteric artery

A
  • leaves the aorta caudal to the celiac artery
  • surrounded proximally by the cranial meenteric plexus of nerves and partly by the cranial mesenteric ganglion
38
Q

renal arteries

A
  • leave the aorta at different levels
  • right one arises cranial to the left in conformity with the more cranial position of the right kidney
  • it is longer than the left and lies dorsal to the caudal vena cava
39
Q

ovarian artery

A
  • paired vessel arises from the aorta about 1/2 way between the renal and external iliac arteries
  • supply the ovart and its bursa and uterine tube and horn
40
Q

testicular artery

A
  • leaves the aorta in the midlumbar region and crosses the ventral surface of the ureter
41
Q

caudal mesenteric artery

A
  • unpaired and arises near the termination of the aorta
  • enters the descending mesocolon and runs caudoventrally to the mesenteric border of the desending colon, where it terminates in 2 branches of similar size
42
Q

portal vein

A

carrues venous blood to the liver from the abdominal viscera such as the stomach, the SI, cecum, colon, pancreas, and the spleen
