Flashcards in Femoral Triangle, Adductor Canal, Vessels and Nerves of the Anterior and Medial Thigh Deck (45)
boundaries of the femoral triangle?
superior - inguinal ligament
medial - lateral border of adductor longus
lateral - medial border of sartorius
roof - fascia lata (deep fascia)
floor - pectineus, iliopsoas
contents of femoral triangle?
femoral nerve as it divides into cutaneous and motor branches
femoral artery with its branches
lateral to medial in femoral triangle?
nerve, artery, vein, lymphatics
prolongation of the transversalis fascia (of abdomen)
-contains femoral artery and vein
nerve NOT in the sheath
medial to femoral vein
-deep inguinal lymph node can usually be found here
fat or intestines my protrude - site of femoral hernia
at the femoral ring
where does femoral nerve course?
groove formed where iliacus and psoas major muscles join
connects the femoral triangle with the popliteal fossa
begins at apex of femoral triangle and passes inferiorly until it reaches an opening in the adductor magnus tendon (adductor hiatus) which communicates with the popliteal fossa
boundaries of the adductor canal?
anteromedial - sartorius and vastoadductor membrane
anterolateral - vastus medialis
posterior - adductor longus superiorly, adductor magnus inferiorly
contents of adductor canal?
motor nerves of vastus medialis (from femoral)
saphenous nerve (from femoral nerve)
as femoral artery and vein enter adductor canal?
artery comes anterior to vein
nerves in adductor canal?
DO NOT exit adductor hiatus
nerve to vastus medialis?
pierces muscle while in canal
pierces wall (vasoadductor membrane) of adductor canal to become cutaneous
descending genicular artery?
branches from femoral artery while in the canal and accompanies saphenous nerve
beginning of the femoral artery?
continuation of external iliac artery
until INGUINAL LIGAMENT
course of femoral artery
femoral triangle to adductor canal
end of the femoral artery?
after exits adductor hiatus, becomes the popliteal artery
branches of the femoral artery?
superficial circumflex iliac artery
superficial epigastric artery
superficial external pudendal artery
deep external pudendal artery
these branches are superior and considered in the units of abdomen and perineum***
deep femoral artery
arises posterolaterally from femoral artery
branches of deep femoral artery?
lateral femoral circumflex
medial femoral circumflex
lateral femoral circumflex artery
arises from deep femoral artery laterally on surface of ilicus muscle and provides three branches
three branches of lateral femoral circumflex artery
ascending branch of lateral femoral circumflex artery
ascends deep to tensor fascia lata muscle
transverse branch of lateral femoral circumflex artery
winds around femur within the substance of the vastus laterails to anastomose with medial femoral circumflex artery, inferior gluteal artery, and first perforating artery
descending branch of lateral femoral circumflex artery
descends on surface of vastus lateralis and ultimately participates with other arteries in genicular anastomosis
medial femoral circumflex artery
arises medially from deep femoral and dives between psoas and pectineus muscles
supplies adductor muscles medially and gives a branch to the acetabulum and head of femur
posteriorly it supplies the deep lateral rotators of the thigh (deep gluteal area) and ends by participating in cruciate anastomosis
arise from lateral surface of deep femoral artery, pierce adductor magnus muscle and pass posterior to the femur to end within the substance of the vastus lateralis muscle
muscular branches may arise from any of the perforating arteries to supply posterior femoral compartment musculature
descending genicular artery
arises from femoral artery just before it passes through the adductor hiatus and divides
division of the descending genicular artery
