What is the attachments of the gluteus maximus?
Illium to iliotibial tract
What is the attachments of the gluteus medius?
Lateral ilium to lateral surface of greater trochanter of femur
What is the attachments of the gluteus minimus?
Lateral ilium to anterior surface of greater trochanter of femur
What is the attachments of the tensor fascia latae?
ASIS to iliotibial tract
What is the attachments of the inferior gemellus?
Ischial tuberosity to medial surface of greater trochanter of femur
What is the attachments of the superior gemellus?
Outside of ischial spine to medial surface of greater trochanter of femur
What is the attachments of the obturator internus?
Pelvic surface of obturator membrane to medial surface of greater trochanter of femur
What is the attachments of the quadratus femoris?
Lateral side of ischial tuberosity to quadrate tubercle on intertrochanteric crest of femur
What is the attachments of the piriformis?
Sacral segments (2-4) to superior border of greater trochanter of femur
What muscles does the superior gluteal artery supply?
Gluteus maximus
Gluteus medius
Gluteus minimus
Piriformis
What muscles does the inferior gluteal artery supply?

What muscles does the medial circumflex femoral artery supply?
Quadratus femoris
Inferior gemellus
What muscles does the internal puedenal artery supply?
Superior gemellus
Obturator internus
What artery is the tensor fascia latae supplied by?
Ascending branch of the lateral circumflex femoral artery
What is the action of the superficial gluteal muscles?
Abduct hip
Medially rotates thigh at hips (except maximus)
What superficial gluteal muscles steady the pelvis on the leg when the opposite leg is raised?
Gluteus medius
Gluteus minimus
What superficial muscle assists in lateral rotation of the thigh?
Gluteus maximus
What do all non superficial gluteal muscles do?
Laterally rotates extended thigh at hips
As well as laterally rotating the extended thigh at hips, what else does the obturator internus and piriformis do?
Abducts flexed thigh at hips
