Cranial rectal

Question 17

Paired arteries (5)

Answer 17

Lumbar a

Phrenicoabdominal a

Renal a

Gonadal a

Deep circumflex iliac

Question 18

Gonadal vein drainage

Answer 18

R testicular/ovarian drains into caudal vena cava

L testicular/ovarian vein drains into left renal vein

Question 19

Splanchnic nerves: pregang or postgang

Answer 19

preganglionic sympathetic nerve fibers from sympathetic trunk

Question 20

Where is splanchnic nerve synapse in ganglia

Answer 20

celiaco-mesenteric ganglion and plexus

Question 21

Two abdominal ganglia

Answer 21

Celiaco-mesenteric ganglion

Caudal mesenteric ganglion

Question 22

Celiaco-mesenteric ganglion and plexus

-Where?

Answer 22

Surrounds celiac artery and cranial mesenteric artery and consists of:

left celiac ganglion

Right celiac ganglion

cranial mesenteric ganglion

Question 23

Most plexuses are:

Answer 23

postganglionic sympathetic and preganglionic parasympathetic

Question 24

Sympathetic path to abdominal viscera

Answer 24

Major and minor splanchnic nerves to celiacomesenteric ganglion and plexus and out to viscera via plexuses which travel along blood vessels

Question 25

T/F All of the “paired arteries” that originate from the abdominal aorta have satellite veins that drain directly or indirectly into the caudal vena cava

Answer 25

T

Question 26

How must the 3 unpaired arteries supplying digestive organs and spleen drain?

Answer 26

Via portal vein.

Portal vein will empty into capillary beds, and blood will carry nutrients via caudal vena cava via hepatic veins

Question 27

Portal veins origin and termination

Answer 27

Arises from capillaries in viscera

Ends in capillaries in the liver

Question 28

Functions of the hepatic portal circulation

Answer 28

1-Carries nutrient rich blood to liver for metabolic synthesis

2-Carries blood high in ammonia and other toxic by products of digestion to the liver for detoxification

Question 29

The liver receives blood from 2 main vessels

Answer 29

Hepatic artery (high in O2, low in nutrients)

Portal vein (low in O2, high in nutrients)
