Vasculer Tree Artries Flashcards
Origin of the AOTA
T12
Termination or bifurcation of the aorta
L4 , at the superorior line between the 2 iliac crests , 2.5 cm below the umblicus
Which are te 3 anterior unpaired branches
Celiac
SmA
ImA
Mention the posterior divisions of the aorta
4 Lumber arteries , median sacral artery. Maybe inferior phrenic lateral or posterior not sure
Adrenals gland arterial supply
Superior suprarenal / adrenal artery > inferior phrenic artery
Middle suprarenal artery > direct branch of the aorta lateral
Inferior suprarenal artery > renal artery .
The 3 posterior to the IVC branches
Renal arteries
Inf phrenic arteries
Lumber arteries
Which branch of the aorta crosses the left common iliac artery
SmA
Common iliac artery stat and termination levels
Bifurcation start at the level of L4
Terminates at the level of L5 / S1 or anterior to the sacroiliac joint .
Anterior relation of the common iliac artery and lateral relations
Inferior hypogastric plexus + small intestines
Posterior relation of the common iliac artrey
Sympathetic trunk
Obturator nerve then goes lateral to the internal iliac artrey
Ileolumber artrey
Ureter relation to the common iliac
A\lateral to it crossing it anteriorly at its bifurcation
Branches of the external iliac artrey
1 ) inf epigastric arteries within the lateral umbilical folds .
2) deep circumflex artrey .
Posterior relations of the external iliac artrey
Psoas major muscle posterior and lateral
What’s crosses the external iliac artrey anteriroly at its origin then bends medically to it
The ureter
Anterior relations of the external iliac artrey at its origin and medically
Ureter
Gonadal vesssels
Ggenital branch of the genitofemoral nerve
Deeper circumflex vein
Round ligament
DUGGr
Medically -> femoral vein .
