Muslces of Anterior thigh Flashcards
pectineus
O: superior ramus of pubis
I: pectineal line of femur, just inferior to the lesser trochanter
INNE: femoral nerve (L2, L3); may recieve a branch from the obturator nerve
sartorious
O: anterior superior iliac spine
I: superior part of medial surface of tibia
INNE: Femoral nerve (L2, L3)
A: FLX, ADD, LAT ROT thigh at hip joint; FLX leg at knee (medially rotates leg when knee is flexed)
Rectus femoris
O: anterior inferior iliac spine
I: via common tendinous (quadriceps tendon) and independent attachments to bas of patella; indirectly via patellar ligament to tibial tuberosity; medial and lateral vasti also attach to tibia and patella via aponeuroses (medial and lateral patellar retinacula
INNE: femoral nerve L2, L3, L4
A: EXT leg at knee; steadies hip joint and helps illiopsoas m FLX thigh
vastus lateralis
O: greater trochanter and lateral lip of linea aspera
I: via common tendinous (quadriceps tendon) and independent attachments to bas of patella; indirectly via patellar ligament to tibial tuberosity; medial and lateral vasti also attach to tibia and patella via aponeuroses (medial and lateral patellar retinacula
INNE: femoral nerve L2, L3, L4
A: EXT leg at kneeI: via common tendinous (quadriceps tendon) and independent attachments to bas of patella; indirectly via patellar ligament to tibial tuberosity; medial and lateral vasti also attach to tibia and patella via aponeuroses (medial and lateral patellar retinacula
INNE: femoral nerve L2, L3, L4
A: EXT leg at knee
vastus medialis
O: intertrochanteric line and medial lip of linea aspera of femur
I: via common tendinous (quadriceps tendon) and independent attachments to bas of patella; indirectly via patellar ligament to tibial tuberosity; medial and lateral vasti also attach to tibia and patella via aponeuroses (medial and lateral patellar retinacula
INNE: femoral nerve L2, L3, L4
A: EXT leg at knee
Vastus intermedius
O: anterior and lateral surafaces of shaft of femur
I: via common tendinous (quadriceps tendon) and independent attachments to bas of patella; indirectly via patellar ligament to tibial tuberosity; medial and lateral vasti also attach to tibia and patella via aponeuroses (medial and lateral patellar retinacula
INNE: femoral nerve L2, L3, L4
A: EXT leg at knee
Gracilis
O: body of the inferior ramus of the pubis
I: superior part of medial surface of tibia
INNE: Obturator nerve (L2, L3)
A: ADD thigh; FLX leg; helps ROT leg MED
Obturator Externus
O: Margins of obturator foramen and obtruator membrane
I: trochanteric fossa of femur
INNE: Obturator nerve (L3, L4)
A: LAT ROT thigh; steadies head of femur in acetabulum
