Canine Abdominal Cavity Flashcards
What are the parietal branches of the abdominal aorta?
Lumbar arteries, phrenicoabdominal arteries, deep circumflex iliac arteries
What are the visceral branches of the abdominal aorta?
Celiac artery, cranial mesenteric artery, Renal arteries, testicular or ovarian arteries, caudal mesenteric artery
The phrenicoabdominal arteries supply what?
Diaphragm and abdominal lateral wall muscles in the cranial half of the abdomen
Lumbar arteries supply what?
Sublumbar muscles, vertebrae, epaxial muscles, spinal cord, and dorsal tissues
Lumbar arteries originate dorsal to what?
Aorta
The deep circumflex iliac arteries supply what?
Sublumbar muscles and abdominal lateral wall muscles in the caudal half of the abdomen
The deep circumflex iliac arteries anastomose with what vessels?
Pelvic limb vessels
What arteries supply the GI tract, pancreas, and spleen?
Visceral branches of abdominal aorta:
Celiac artery, cranial mesenteric artery, caudal mesenteric artery
What are the three branches of the celiac artery?
Hepatic artery, left gastric artery, and splenic artery
What are the terminal branches of the abdominal aorta?
External iliac arteries, internal iliac arteries, median sacral artery
The external iliac arteries mainly supply what?
The pelvic limb
The internal iliac arteries mainly supply what?
Pelvic organs
The median sacral artery supplies what and then continues into the tail?
Sacrum
What are the hypaxial Sublumbar muscles?
Quadratus lumborum muscle, psoas minor muscle, psoas major muscle, iliacus muscle
Describe the formation of the iliopsoas muscle.
Formed by the fusion of psoas major and iliacus muscles
The celiac artery supplies what?
Stomach, spleen, liver, pancreas, duodenum
The cranial mesenteric artery supplies what?
Small and large intestine, pancreas
The Renal arteries supply what?
Kidneys and perirenal tissues
The testicular / ovarian arteries supply what?
Testicle, epididymis, ductus deferens/ ovary, uterine tube, cranial part of uterine horn
The caudal mesenteric artery supplies what?
Descending colon, rectum
Describe the cranial and caudal epigastric arteries. Include their origins and the tissue/organs they supply
Two arteries that supply the mammary glands and anastomose in the umbilical area
Cranial originates from internal thoracic artery
Caudal originates from external pudendal artery
In what vein does the left testicular vein / left ovarian vein open into?
Left renal vein
Explain the concept of the portal vein.
Organs drained via the portal vein, the blood enters the liver and then using the hepatic veins to connect with the caudal vena cava
Can hepatic veins be seen without dissecting away the hepatic tissue around it?
No
They do not have an extrahepatic portion
The hepatic veins join what vessel before it crosses over into the diaphragm?
Caudal vena cava
How does the lymphatic fluid contained into the cisterna chyli continue traveling in the thoracic cavity and later join with the vein system close to the thoracic inlet?
Fluid contained in the cisterna chyli travels through the thoracic cavity via the thoracic duct which ascends through the thorax and eventually empties into the venous system at the junction of the left jugular and subclavian veins near the thoracic inlet
What territories/organs end into the cisterna chyli?
Lower extremities, intra-abdominal organs, kidneys, and abdominal wall
What veins drain into the caudal vena cava?
Lumbar veins, deep circumflex iliac veins, common iliac veins, hepatic veins, phrenicoabdominal veins, renal veins, right testicular or ovarian veins
What veins join together to form the common iliac veins?
External and internal iliac veins
What vessel is closer to the right kidney? The left kidney?
Right - caudal vena cava
Left - aorta
What organs are drained by the portal vein?
Spleen, pancreas, stomach, small intestine, and large intestine
