What muscles make up the Quadriceps femoris
Rectus femoris
Vastus lateralis
Vastus medialis
Vastus intermedius
- all attach to the tibial tuberosity via the patellar ligament (tendon)
- all 4 extend the knee

“Say Grace before Tea”
- Sartorius
- Gracilis
- semiTendinosus
Attachments & Actions of Gluteus Maximus
Attach:
- most fibres attach distally to the IT Band
- some fibres attach distally to the gluteal tuberosity of femur
Action:
- extends hip, laterally rotates hip
Attachments & Actions of Gluteus Medius
Attach:
- between the posterior and anterior gluteal lines
- lateral surface or the greater trochanter
Action:
- abducts hip, medially rotates hip
Attachments & Actions of Gluteus Minimus
Attach:
- O: between anterior and inferior gluteal line
I: lateral surface of the greater trochanter
Action:
- abducts hip, medially rotates hip
Attachments & Actions of Tensor Fasciae Latae (TFL)
Attach:
- fibres attach distally to the iliotibial tract
- anterior portion of the iliac crest
Action:
- flexes hip, abducts hip, medially rotates hip
Attachments & Actions of Piriformis
Attach: - medial attachment inside the pelvic girdle on the anterior surface of the sacrum - greater trochanter Action: - laterally rotates hip
Attachments & Actions of Obturator Internus
Attach: - medial attachment inside the pelvic girdle around the obturator foramen - greater trochanter Action: - laterally rotates hip
Attachments & Actions of Obturator externus
Attach: - around the obturator foramen on the outside of the pelvic girdle. - greater trochanter Action: - laterally rotates hip
Attachments & Actions of Superior Gemellus
Attach: - ischial spine - greater trochanter Action: - laterally rotates hip
Attachments & Actions of Inferior Gemellus
Attach: - ischial tuberosity - greater trochanter Action: - laterally rotates hip
Attachments & Actions of Quadratus Femoris
Attach: - ischial tuberosity - intertrochanteric crest Action: - laterally rotates hip
Main actions & attachments of the Anterior muscles of the Thigh
