(7)
first branch off femoral
superficial epigastric
where does the superficial epigastric course?
- originates 1 cm inferior to inguinal ligament
- passes through femoral sheath and proceeds superiorly, anterior to inguinal ligament
- terminates by anastomosing with inferior epigastric a
the superficial epigastric a is _______ to the vein
lateral
blood supply to anterior abdominal wall below umbilicus
superficial epigastric a
skin and superficial fascia
smallest branch of femoral a
superficial circumflex iliac
course of superfiical circumflex iliac
- originates anterolateral aspect of femoral a slightly below the superfiicial epigastric
- travels laterally (paralleling the inguinal ligament) to the iliac crest
what does the superficial circumflex iliac anatastomose with
- deep circumflex iliac
- superior gluteal
- lateral femoral circumflex
originates from medial side of femoral a across from the origin of superficial circumflex iliac
superficial external pudendal
course of superficial external pudendal a
- travels medially
- crosse spermatic cord
- supplies perineal structures
- supplies lower abdominal wall
- anastomoses with branches of internal pudendal a
what m get branches originating directly from femoral a
- vastus medialis
- sartorius
- adductor muscles
largest branch of femoral a
profundus femoris
where does the profundus femoris originate
- 2-5 cm distal to inguinal ligament on LATERAL aspect
describe the course of profundus femoris
- travels inferiorly
- spirals posterior to femoral a, then medial to it
- lower 1/3 of thigh it is posterior to adductor longus
- terminates as fourth perforting a
how does the profundus femoris terminate
- small branch entering the adductor magnus m
- known as fourth perforating a
branches off of the profundus femoris
- lateral femoral circumflex
- medial femoral circumflex
- perforating (4)
- muscular branches
branches of lateral femoral circumflex
- ascending branch
- transverse branch
- descending branch
origin of lateral femoral circumflex
- lateral side of produndus femoris
- 20% originates from stem of femoral a
course of lateral femoral circumflex
laterally deep to rectus femoris and sartorius muscles
describe the ascending branch of lateral femoral circumflex a
- travels superolaterally deep to fascia lata
- lateral side of upper thigh
- anastomsoes with branches of superior gluteal and deep circumflex iliac aa
smallest branch off lateral femoral circumflex
transverse branch
course of transverse branch of lateral femoral circumflex
- travels laterally around femur inferior to greater trochanter
- pierces vastus lateralis
- posteriro aspect of thigh
- participates in cruciate anastomosis
what a participate in cruciate anastomsis
- transverse branch of lateral femoral circumflex
- femoral circumflex
- inferior gluteal a
- first perforating a
FFIT
course of descending branch of lateral femoral circumflex
- courses inferiorly below rectus femoris
- supplies vastus lateralis m
- reaches knee joint to anastomose with lateral genicular branch of popliteal a
what does the descending branch of lateral femoral circumflex anastomose with
lateral genicular branch of popliteal a
origin of medial femoral circumflex
medial aspect of profundus femoirs
255 originates directly from femroal a
course of medial femoral circumflex
- medially disappears b/w pectineus and psoas major m
- winds around medial aspect of femur
- supplies muslces
- contributes to cruciate anastomosis
- gives acetabular branch
what m does the medial femoral circumflex supply
- adductor muscles
