Upper Leg and Hip Anatomy Flashcards
Vastus Medialis
Origin: medial femur
Insertion: tibial tuberosity via patella tendon
Action: extends knee
Vastus Lateralis
Origin: lateral femur
Insertion: tibial tuberosity via patella tendon
Action: extends knee
Vastus Intermedius
Origin: anterior femur
Insertion: tibial tuberosity via the patella tendon
Action: extends knee
Rectus Femoris
Origin: anterior inferior iliac spine
Insertion: tibial tuberosity via the patella tendon
Action: flexes hip and extends knee
Semimembranosus
Origin: ischial tuberosity
Insertion: posterior portion of the medial condyle of the tibia
Action: flexes knee and extends hip
Semitendinosus
Origin: ischial tuberosity
Insertion: anteromedial portion of proximal tibia
Action: flexes knee and extends hip
Biceps Femoris
Origin: ischial tuberosity and linea aspera of the femur
Insertion: fibular head
Action: flexes knee, extends hip, laterally rotates leg
Sartorius
Origin: anterior superior iliac spine
Insertion: anteromedial portion of proximal tibia
Action: flexes, externally rotates and abducts hip
Gluteus Maximus
Origin: lateral sacrum and gluteal surface of ilium
Insertion: gluteal tuberosity of femur and IT band
Action: extends and laterally rotates femur
Gluteus Medius
Origin: gluteal surface of ilium
Insertion: greater trochanter
Action: abducts femur
Gluteus Minimus
Origin: gluteal surface of ilium
Insertion: greater trochanter
Action: abducts and medially rotates femur
Piriformis
Origin: anterior sacrum
Insertion: greater trochanter
Action: abducts and externally rotates femur
Tensor Fascia Latae
Origin: anterior superior iliac spine
Insertion: lateral tibia via IT band
Action: flexes and abducts hip
Adductor Longus
Origin: armies of pubis
Insertion: middle 1/3 of linea aspera of femur
Action: adducts femur
Adductor Brevis
Origin: ramis of pubis
Insertion: lesser trochanter and linea aspera of femur
Action: adducts femur
