URR LE A Anatomy Flashcards
inner vessel, endothelial cells, and basement membrane
tunica intima
middle of the vessel, muscle
tunica media
outer of the vessel, epithelial cells, contains vaso vasorum, connects vessel vessel to surrounding structure
tunica adventitia/externa
what is a vaso vasorum?
cap beds that feed/drain the vessel wall
how does blood from from arterioles to veins?
A-> arterioles->capillary beds-> venules-> veins
capillaries consist of intimal tissue only to allow for what?
perfusion
capillary refill time increases with what?
increased resistance
the common iliac arteries supply what?
legs and pelvis
-high resistive
internal iliac arteries/hypogastric A supply what?
pelvic organs (NOT GONADS)
-triphasic or biphasic waveform, low resistive
what does the external iliac artery supply?
extremities
-sourses along medial side of psoas
-triphasic, high resistance
-lat branches include epigastric A and deep circumflex A that supply abd wall muscles/skin, provide potential for collateralization with obstruction of EIA
the CFA begins where?
at the inguinal ligament
the SFA courses where?
medial in the thigh through adductor hiatus (Hunters canal)
-after passes through, becomes pop A
profunda fem A supplies what
branches supply quads and other thigh muscles
-provides potential for collat flow with fem A disease
when scanning the pop A, where should it be in relation to vein?
A should be post to V, in reality, is anterior to V
the anterior tibial As should be where?
courses across interosseous membrane of calf to become dorsalis pedis (DPA)
