what is the terminal branch of the inferior mesenteric artery?
superior rectal artery that vascularizes the upper portion of the rectum
in the rectum we have a shared vascularization between the hypogastric artery and the inferior mesenteric, why?
the superior rectal artery (superior portion of rectum) is the terminal branch of the inferior mesenteric artery
the middle and inferior rectal arteries are branches of the internal pudendal artery that come from the hypogastric
which rectal vein drains into the hepatic portal vein?
superior rectal vein
branch of inferior mesenteric vein
joins the splenic vein, then the superior mesenteric and forms the portal vein
the inguinal ligament goes from where to where?
from the anterior superior iliac spine to the pubic tubercle
position of the inguinal canal respect to the inguinal ligament
the inguinal canal is above the inguinal ligament
the largest portion of the inguinal passage is? and is occupied by?
the lateral part
the iliopsoas muscle
the iliopsoas muscle is made by the fusion of which muscles?
iliacus and psoas major, which fuse while going down passing into the lateral part of the inguinal passage
the medial portion of the vascular passage is occupied by?
smaller than the lateral one
occupied by the external iliac artery and vein
medial portion=vascular passage
where does the femoral nerve travel?
into the lateral part of the inguinal canal together with the iliopsoas
the origin of the femoral artery and vein is contained where?
into a triangle called scarpa triangle right below the inguinal ligament
the base of the triangle is on top and is the inguinal ligament
the apex Is at the bottom and the sides are muscular in nature
laterally we can spot the femoral nerve that passes with the muscles
where do they put endovascular instruments to reach the coronary arteries?
inside the femoral artery
that converge into the aorta
the posterior muscle of the thigh is vascularized by?
the deep femoral artery
why do the femoral vessels enter into the adductor canal?
to move from the anteromedial part of the thigh to the posterior one. the posterior part is called popliteal region and the two vessels there change their name into popliteal artery and vein
where do the femoral artery and vein become popliteal vessels?
in the popliteal fossa
they are protected by muscles and are not much superficial
the popliteal artery branches into
anteriorly: anterior tibial artery
vvascularizes anterior leg and dorsal foot
posteriorly: posterior tibial artery
vascularizes posterior leg and medial plantar foot
the posterior tibial artery branches into
fibular artery that vascularizes the lateral portion of the plantar foot and the lateral muscles of the leg
great saphenous vein
originates from the dorsal venous arch of the foot and goes up until below the scarpa triangle where it becomes femoral vein
small saphenous vein
originates from the popliteal vein and ravels in between the two muscle bellies of the gastrocnemius
