L5: Vessels & Nerves of Lower Extremity Flashcards
femoral artery is the continuation of the ?
external iliac artery
origin of femoral artery
begins deep to inguinal lig.
enclosed w/in femoral sheath
becomes popliteal artery at adductor hiatus
proximal branches of femoral art.
superficial epigastric a
superficial circumflex iliac a
superficial external pudendal a.
superficial epigastric artery
passes thru saphenous hiatus
crosses inguinal lig. toward umbilicus
anastomoses w/ inf. epigastric art.
superficial circumflex iliac artery
passes thru saphenous hiatus
passes along inguinal lig. towards ASIS
anastomoses w/ deep circumflex iliac artery
superficial external pudendal artery
passes thru saphenous hiatus
passes medially toward external genitalia
deep branches of femoral artery
deep external pudendal
descending genicular
profundal femoral or deep femoral
branches of produnda femora
medial femoral circumflex
lat. femoral circumflex
perforating arteries - 3
descending genicular
deep external pudendal
passes medially acros pectineus and adductor longus
becomes superficial to supply external genitalia
descending genicular artery
arises in adductor canal
musculoarticular branch – part of genicular anastomoses
saphenous branch – runs w/ saphenous nerve
profundal femora artery
arises from deep side of femoral art. w/in f triangle
largest branch of femoral a.
passes post. to adductor longus
terminates as a 4th terminating artery
medial femoral circumflex artery
may come directly off femoral a.
leaves femoral triangle between iliopsoas and pectineus
supplies hip joint, upper thigh, glutes
branches of medial femoral circumflex artery
ascending branch – anastomose w/ inf. gluteal
transverse branch – anastomose w/ lat. femoral circumflex a.
lateral femoral circumflex artery
may come directly off femoral a.
passes laterally deep to rectus femoris and sartorius
supplies hip joint, upper thigh, glutes
branches of lateral femoral circumflex artery
ascending branch – anas w/ superior gluteal a.
transverse branch – anas w/ medial femoral circ. a.
descending branch – anas w/ genicular arteries
popliteal artery is a continuation of the ?
femoral artery
popliteal artery
begins at adductor hiatus
ends at inf. border of popliteus muscle
most anterior structure in popliteal fossa
branches of popliteal artery at ending
branches into anterior and posterior tibial arteries
branches off popliteal artery
med. and lat. superior genicular arteries
med. and lat. inferior genicular arteries
middle genicular a. and sural(calf) arteries
what is the cruciate anastomosis?
joins the internal iliac to femoral artery
a bypass for femoral or external iliac arteries
cruciate anastomosis includes branches from ?
medial femoral circumflex
lat. femoral circumflex
inferior gluteal a.
first perforating artery
obturator artery
arises from internal iliac in pelvis
enters thigh thru obturator canal
accompanied by ant/post obturator nerve branches
obturator artery gives rise to ?
anterior and poster branches
acetabular artery
acetabular artery
to head of femur via ligamentum teres
contributors to genicular anastomosis
- genicular branches of popliteal a.
- descending branches of femoral and deep femoral
- ascending branches of ant/post tibial arteries
where is the genicular anastomosis?
back of the knee
between 2 condyles
