Femoral triangle, anterior and medial thigh Flashcards
What is the role of the fascia lata?
limits the outward expansion of contracting thigh muscles
aids venous return from lower limb
provides stability to knee joint in extended and partially flexed positions through the iliotibial tract
State the origin, insertion, innervation and action of tensor fasciae latae
origin = lateral crest of ileum between ASIS and tubercle of crest
insertion = iliotibial tract of fascia lata
superior gluteal nerve - L4,L5,S1
stabilises the knee in extension
What is the iliotibial tract?
a thickening of the fascia lata band of tissue that runs alongside the outside of the thigh from the hip to the knee
State the superior, lateral and medial borders of the femoral triangle
superior = inguinal ligament
lateral = sartorius muscle
medial = adductor longus
State the contents of the femoral triangle
femoral nerve
femoral vein
femoral artery
State the origin, insertion, innervation and action of pectineus
origin = pectineal line and adjacent bone of pelvis
insertion = oblique line from lesser trochanter to the linea aspera of the femur
femoral nerve L2,L3
adducts and flexes thigh at hip joint
State the origin, insertion, innervation and action of psoas major
origin = lumbar transverse processes and intervertebral discs and adjacent bodies from T12-L5
insertion = lesser trochanter of femur
anterior rami L1,L2,L3
flexes the thigh at the hip joint
State the origin, insertion, innervation and action of iliacus
origin = iliac fossa
insertion = lesser trochanter of femur via iliopsoas tendon
femoral nerve
hip flexion and stabilisation of the hip
What does the deep femoral artery give rise to
medial and lateral circumflex
What does the femoral artery give rise to
deep femoral and superficial femoral artery
Where does the popliteal artery run
between popliteus and gastrocnemius
What drains into the small saphenous vein
dorsal venous arch
plantar venous network
where does the great saphenous vein run
the entire length of the leg and thigh along the medial aspect
State the origin, innervation, insertion and action of sartorius
origin = ASIS
insertion = medial surface of tibia, inferomedial to the tibial tuberosity
femoral nerve L2,L3
flexes thigh at hip joint and leg at knee joint
State the origin, insertion, innervation and action of vastus medialis
origin = upper 2/3 of anterior lateral femur
insertion = QF tendon, lateral margin of patella and lateral condyle of tibia
femoral nerve L2,L3,L4
extends leg at knee joint
State the origin, insertion, innervation and action of rectus femoris
origin = straight head from ASIS, reflected head from the ileum just above the acetabulum
insertion = quadriceps femoris tendon
femoral nerve L2,L3,L4
flexes thigh at hip and extends leg at knee
State the origin, insertion, innervation and action of vastus lateral is
origin = femur (lateral part of intertrochantic line, margin of greater trochanter, lateral margin of gluteal tuberosity, lateral lip of linea aspera)
insertion = QF tendon and lateral margin of patella
femoral nerve L2,L3,L4
extends leg at the knee joint
State the origin, insertio, innervation and action of adductor brevis
origin = external surface of pubis and inferior pubic ramus
insertion = posterior proximal femur and upper 1/3 linea aspera
obturator nerve L2,L3
adduction of the thigh
State the origin, insertion, innervation and action of adductor longus
origin = external surface of body of pubis
insertion = linea aspera on middle 1/3 of shaft of femur
obturator nerve L2,L3,L4
adduction of the thigh
State the origin, insertion, innervation and action of gracilis
origin = external surface of body of pubis, inferior pubic ramus and ramus of ischium
insertion = medial surface of proximal shaft of tibia
obturator nerve L2,L3
adduction of thigh at hip and flexion of leg at the knee
State the origin, insertion, innervation and action of adductor magnus
origin = adductor part = ischiopubic ramus, hamstring part = ischial tuberosity
insertion = posterior proximal femur, linea aspera and medial supracondylar line
obturator nerve L2,L3,L4
adductor (adduction and flexion of the thigh)
hamstring (adduction and extension of the thigh)
What does the obturator nerve innervated
the medial compartment of adductors
