|
Biceps femoris |
O: long head; ischial tuberosity, short head; linea aspora and distal femur I: by common tendon into the head of the fibula and lateral condyle of the tibia A: thigh extension, knee flexion, lateral leg rotation |
|
|
Semipembranosus |
O: ischial tuberosity I: medial condyle of tibia A: thigh extension and knee flexion, medial leg rotation |
|
|
Semitendinosus |
O: Ischial tuberosity I: medial aspect of upper tibial shaft A: thigh extension, knee flexion, medial leg rotation |
|
|
Tensor fasciae latae |
O: anterior aspect of iliac crest and anterior superior iliac spine I: iliotibial tract A: flexes and abducts the thigh, medial rotation of thigh |
|
|
Gluteus medius |
O: upper lateral surface of ilium I: lateral aspect of greater trochanter of femur A: abducts and medically rotates thigh |
|
|
Gluteus maximus |
O: ilium and dorsal sacrum and coccyx I: gluteal tuberosity of femur: iliotibial tract A: major thigh extender, lateral rotation of thigh |
|
|
External oblique |
O: By flashy strips from outer surfaces of lower 8 ribs I: linea alba, pubic tubercle and iliac crest A: simultaneous activation; aids rectus abdominus in flexing vertebral column and in compressing abdominal wall. Individual activation; trunk rotation and lateral flexion |
|
|
Internal oblique |
O: lumbodorsal fascia, iliac crest, and inguinal ligament I: linea alba, pubic crest and last three ribs A: simultaneous activation; aids rectus abdominus in flexing vertebral column and in compressing abdominal wall. Individual activation; trunk rotation and lateral flexion |
|
|
Rectus abdominus |
O: pubic crest symphysis I: xiphoid process of cartilage of ribs 5-7 A: flex and rotate lumbar region, fix and depress ribs, stabilize pelvis during walking and increases intra-abdominal pressure |
|
|
Transverse abdominus |
O: inguinal ligament, lumbosacral fascia, cartilage of last 6 ribs I: linea alba, pubic crest A: compresses abdominal content |
|
|
Sartorius |
O: anterior superior iliac spine I: winds around medial aspect of knee and inserts into medial aspect of proximal tibia A: hip flexion, thigh lateral rotation, and weak knee flexion |
|
|
Rectus femoris |
O: ASIS I: base of patella and tibial tuberosity via patellar tendon A: knee extension; hip flexion |
|
|
Vastus lateralis |
O: greater trochanter of femur, intertrochanteric line, linea aspea I: tibial tuberosity via patellar tendon A: knee extension |
|
|
Vastus intermedius |
O: anterior and lateral surfaces of proximal femoral shaft I: tibial tuberosity via patellar tendon A: knee extension |
|
|
Vastus medialus |
O: linea aspera, intertrochanteric line I: tibial tuberosity via patellar tendon A: knee extension, lower fibers stabilize patella |
|
|
Tibialis Anterior |
O: lateral condyle and upper 2/3 of tibia; interosseus membrane I: inferior surface of 1st cuneiform and 1st metatarsal A: prime dorsi flexor, foot inverter, assist with longitudinal arch support |
|
|
Soleus |
O: cone shaped origin from superior tibia, fibia, and interosseus membrane I: calcaneus via Achilles' tendon A: plantar flexion |
|
|
Gastrocnemus |
O: by 2 heads from medial and lateral femoral condyles I: calcaneus via Achilles' tendon A: plantar flexion, assists with knee flexion |
