Femoral triangle, ADductor canal, vessels and nerves of anterior and medial thigh Flashcards
Boundaries of femoral triangle
superior: inguinal lig
medial: lateral border of ADductor longs
lateral: medial border of sartorius
roof: fascia kata
floor: pectineus, iliopsoas
general contents lateral to medial
femoral nerve
femoral artery
femoral vein
lymphatics
what is not included in the femoral sheath
the nerve
where is a femoral hernia
protruding abdomen through femoral ring
where does the femoral nerve course
in the groove formed where iliacs and psoas major mm join
what does the adductor canal connect
compartment of femoral triangle with the popliteal fossa
boundaries of adductor canal
anteromedially: sartorius and vastoadductor membrane
anterolaterally: vastus medialis
posteriorly: adductor longus superiorly, adductor magnus inferiorly
contents of adductor canal
femoral artery, femoral vein, motor nerve to vastus medialis, saphenous nerve
what structure in the adductor canal does not exit adductor hiatus
the femoral nerve
where does the saphenous n pierce
medial wall of adductor canal to become cutaneous
where does the descending genicular a originate
branches from femoral a while in the canal and accompanies the saphenous n
what does the femoral a become distally
popliteal artery when exits adductor hiatus
why does the femoral a move more anteriorly as it reaches the popliteal fossa
more protected in this position
what are the bracnhes of the femoral a
superficial circumflex iliac a superficial epigastric a superficial external pudendal a deep external pudendal a deep profunda femurs a descending genicular a
what are the branches of profunda femoral
lateral femoral circumflex a, medial femoral circumflex a, perforating aa
what are the branches of lateral femoral circumflex a and what do they supply
ascending- tensor fascia lata
transverse- anastomose with medial circumflex branches
descending- genicular anastomosis
what does the medial femoral circumflex a supply
ADductor mm medially and gives a branch to acetabelum
posteriorly supplies deep lateral rotators
ends in cruciate anastomosis
what do the perforating branches of femoral a supply
vastus lateralis, posterior femoral compartment
what are the branches of descending genicular a
articular branch and saphenous branch
what does the articular branch of genicular a supply
vastus medialis and forms genicular anastomose
what does the saphenous branch of genicular a supply
subcutaneous areas of upper medial portion of leg
what is the femoral v a continuation of
popliteal v
where does the obturator a branch from
internal iliac a
what m is the obturator a deep to
obturator externus
What are the branches of obturator a and what do they supply
anterior and posterior encircle the obturator foramen deep and anastomose
the acetabelar branch supplies acetabelum and an a to the head of femur via ligamentum trees femoris
what is the obturator v a tributary to
internal iliac v
while in the femoral triangle what does the femoral n provide
intermediate and medial femoral cutaneous branches and motor branches to pectineus and sartorial, rectus femoris, vastus muscles and articularis genu
what branches of femoral nerve enter adductor canal
motor branch to vastus medial is m and the saphenous n (L4)
what does the saphenous n supply cutaneously
medial portion of leg and foot and posterior portion of dorsum of foot
What ventral rami are included in obturator n
L2 L3 L4
What are the two branches of obturator n
anterior and posterior
what does the anterior division of obturator n inn
adductor longus and brevis, gracilis and sometimes pectinous also cutaneous to medial surface of thigh
what does the posterior division of obturator n inn
obturator externus, portion of adductor magnus and sends articular branch to knee
