|
Pectineus
|
Origin: sup ramus of pubis
Insertion: pectineal line of femur, just inferior to lesser trochanter Innervation: femoral nerve Function: Adducts and flexes thigh; assists with medial rotation of thigh |
|
|
Iliopsoas: Psoas major
|
Origin: sides of T12-L5 vertebrae and discs between them; transverse processes of all lumbar vertebrae
Insertion: lesser trochanter of femur Innervation: ant rami of lumbar nerves L1 L2 L3 Function: act conjointly in flexing thigh at hip and in stabilizing this joint |
|
|
Iliopsoas: Psoas minor
|
Origin: sides of t12-l1 vertebrae and intervertebral discs
Insertion: pectineal line, iliopectineal eminence via iliopectineal arch Innervation: ant rami of lumber nerves l1 l2 Function: act conjointly in flexing thigh |
|
|
Iliopsoas: Iliacus
|
Origin: iliac crest, iliac fossa, ala of sacrum, and ant sacroiliac ligaments
Insertion: tendon of psoas major, lesser trochanter, and femur distal to it Innervation: Femoral nerve Function: act conjointly to flex thigh |
|
|
Sartorius
|
Origin: ant sup iliac spine and sup part of notch inf to it
Insertion: sup part of medial surface of tibia Innervation: femoral nerve Function: flexes, abducts, and laterally rotates thigh at hip joint; flexes leg at knee joint |
|
|
Quadriceps femoris: Rectus femoris
|
Origin: ant inf iliac spine and ilium sup to acetabulum
Insertion: via common tendinous and independent attachments to base of patella; indirectly via patellar ligament to tibial tuberosity Innervation: femoral nerve Function: extend leg at knee joint; steadies hip joint and helps iliopsoas flex thigh |
|
|
Quadriceps femoris: Vastus lateralis
|
Origin: greater trochanter and lat lip of linea aspera of femur
Insertion: base of patella, patellar lig to tibial tub. also attaches to tibia and patella via aponeuroses Innervation: femoral nerve Function: extend leg at knee joint |
|
|
Quadriceps femoris: Vastus medialis
|
Origin: intertrochanteric line and medial lip of linea aspera of femur
Insertion: base of patella, patella lig to tibial tub. also attaches to tibia and patella via aponeurosses Innervation: femoral nerve Function: extend knee at leg joint |
|
|
Quadriceps femoris: Vastus intermedius
|
Origin: ant and lat surf of shaft of femur
Insertion: base of patella, patella lig to tibial tub. also attaches to tibia and patella via aponeuroses Innervation: femoral nerve Function: extend leg at knee joint |
