where does the common iliac a split?
b/w L5-S1
larger terminal branch of common iliac
external iliac a
branches off external iliac a
- inferior epigastric a
- deep circumflex iliac a
- becomes the femoral a
branches off the femoral a
- superficial external pudendal a
- deep external pudendal a
- profunda femoris
largest branch off femoral a
profunda femoris
comes off 2-5 cm distal to inguinal ligament
course of profunda femoris
from lateral aspect of femoral a
spirals posterioringerior then to medial
what does the ascending branch of lateral femoral circumlex anastomose with?
- medial femoral circumflex
- superiof gluteal
- deep circumflex iliac
the ascending branch of lateral femoral circumflex enters the fibrous capsule as…
retinacular branches
most important a for adults neck of femur ***
medial femoral circumflex
how often does the medial femoral circumflex come off the femoral?
25%
supplies fat in acetabular foss and around round ligament to head of femur
acetabular branches oof medial femoral circumflex
joins obturator n lateral wall pelvis to enter obturator canal
obturator a
w/ ligament head of femus, supplying the head of femur
foveolar branch of obturator a
needed for kids, but not for adults head of femur
foveolar branch
vein that enters the greater sciatic foramen inferior to the piriformis
inferior gluteal v
- this v anastomoses with medial femoral circumflex and 1st perforating
