Muscle | Origin | Insertion | Innervation | Actions |
Gracilis | Body and inferior ramus of pubis | Upper part of medial surface of shaft of tibia | Anterior branch of obturator nerve | Adduction of thigh at hip joint; flexion and medial rotation of leg at knee joint |
Adductor longus | anterior aspect of body of pubis | linea aspera | anterior branch of obturator nerve | adduction and flexion of thigh at hip join; lateral rotation of thigh at hip joint (?) |
Adductor brevious | body and inferior ramus of pubis | linea aspera | anterior branch of obturator nerve | adduction and flexion of thigh at hip joint; lateral rotation of thigh at hip joint (?) |
Adduction Magnus | inferior ramus of pubis, ramus of ischium and ischial tuberosity | linea aspera, medial supracondylar line and adductor tubercle of femur | adductor part: anterior branch of obturator nerve; hamstring part: tibial division of sciatic nerve | adduction and flexion of thigh at hip joint |
Obturator Externus | outer surface of obturator membrane and pubic and ischial rami | medial surface of greater trochanter | posterior branch of obturator nerve | lateral rotation of thigh at hip joint |
Sartorius | ASIS | upper part of medial surface of shaft of tibia | femoral nerve | flexion, abduction and lateral rotation of thigh at hip joint |
Tensor Fasciae Latae | outer edge of iliac crest between ASIS and tubercle of iliac crest | iliotibial tract | superior gluteal nerve | helps extend knee via iliotibial tract; helps with flexion, abduction, and medial rotation of thigh at hip joint; acts from below to steady pelvis on head of femur |
Iliopsoas | psoas: transverse processes of T12-L5; Iliacus part: iliac fossa | lesser trochanter of femur | psoas: ventral rami L1-L3; iliacus: femoral nerve | flexion of thigh at hip; flexion of trunk on thighs; lateral roation of thigh at hip joint |
Pectineus | pectineal line of superior ramus of pubis | pectineal line of femur | femoral nerve | flexion and adduction of thigh at hip joint |
Rectus femoris | straight head: AIIS; reflected head: ilium immediately above acetabulum | common tendon of insertion into patellar ligament int tibial tuberosity | femoral nerve | extention of leg at knee joint; flexion of thigh at hip joint |
Vastus lateralis | upper part of intertrochanteric line, baseof greater trochanter and lateral lip of linea aspera | common tendon of insertion into patellar ligament int tibial tuberosity | femoral nerve | extension of leg at knee joint; strengthen knee via retinacula |
Vastus medialis | lower part of intertrocanteric line, medial to the pectineal line and along medial lip of linea aspera | common tendon of insertion into patellar ligament int tibial tuberosity | femoral nerve | extension of leg at knee joint; strengthen knee via retinacula; prevent lateral movement of patella |
Vastus intermedius | anterior and lateral sufaces of shaft of femur | common tendon of insertion into patellar ligament int tibial tuberosity | femoral nerve | extension of leg at knee joint |
