covers the organs suspended in these cavities

Question 3

connecting peritoneum

Answer 3

double sheet of peritoneum that connects the parietal and visceral layers or the visceral layers of adjacent organs, forming peritoneal folds referred to as mesenteries, omenta, or ligaments

omentum

Answer 4

connecting peritoneum that attaches the stomch to the body wall or other organs

part of the ventral mesogastrium, loosely spans the distance from the lesser curvature of the stomach to the porta of the liver

Question 7

Answer 7

formed by the omental and the adjacent organs

Question 8

Question 9

mesoduodenum

Answer 9

originates at the dorsal abdominal wall and the root of the mesentery and extends to the duodenum

duodenocolic fold

Answer 10

ascending duodenum is secondarily attached to the mesocolon of the descending colon by this

Question 11

mesentery

Answer 11

attaches to the abdominal wall opposite of the second lumbar vertebra

Question 12

root of the mesentery

Answer 12

short periotneal attachment

Question 13

ascending, transverse, and desending mesocolons

Answer 13

connect the ascending, transverse, and descending volons to the dorsal body wall

Question 14

right triangular ligament

Answer 14

extends from the right crus of the diaphragm above the central tendinous part to the right lateral lobe of the liver

Question 15

Question 16

coronary ligament

Answer 16

sheet of peritoneum that passes between the diaphragm and the liver around the caudal vena cava and hepatic veins

Question 17

falciform ligament

Answer 17

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

Question 18

vagus nerve

Answer 18

carries both sensory and motor axons from and to the viscera

Question 19

dorsal and ventral branches of vagus nerve

Question 20

dorsal vagal trunk

Answer 20

dorsal branches unite near the diaphragm

Question 21

ventral vagal trunk

Answer 21

ventral branches unite caudal to the root of the lung

Question 22

celiac branch

Answer 22

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

Question 23

splanchnic nerves

Answer 23

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

Question 24

major splanchnic nerve

Answer 24

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

Question 25

minor splanchnic nerves

Answer 25

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

Question 26

lumbar splanchnic nerves

Answer 26

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

Question 27

celic ganglia

Answer 27

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

Question 28

cranial mesenteric ganglion

Answer 28

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

Question 29

celiacomesenteric ganglion and plexus

Question 30

caudal mesenteric ganglion

Answer 30

located ventral to the aorta around the caudal mesenteric artery

Question 31

caudal mesenteric plexus

Answer 31

some nerves leaving the ganglion continue along the artery

Question 32

right and left hypogastric nerves

Answer 32

leave the caudal mesenteric ganglion and course caudally near the ureters

Question 33

celiac artery

Answer 33

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

Question 34

hepatic artery

Answer 34

* 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

Question 35

left gastric artery

Answer 35

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

Question 36

splenic artery

Answer 36

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

Question 37

cranial mesenteric artery

Answer 37

* leaves the aorta caudal to the celiac artery * surrounded proximally by the cranial meenteric plexus of nerves and partly by the cranial mesenteric ganglion

Question 38

renal arteries

Answer 38

* 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

Question 39

ovarian artery

Answer 39

* 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
