- With Iliacus-forms Iliopsoas-strongest hip flexor
-
Iliacus
- Origin-iliac fossa of ilium
- Insertion-lesser trochanter of femur
- Actions-hip flexion
- With psoas major-forms iliopsoas-strongest hip flexor
-
Sartorius
- Origin-anterior superior iliac spine
- Insertion-upper medial shaft of tibia
- Actions-assists hip flexion, assists hip abd, assists hip ER, assists knee flexion, assists medial rotation of tibia when knee flexed and foot free
-
Hip External Rotators
- Origin-piriformis-anterior sacrum & sacral ligament, gemellus superior-ischial spine, gemellus inferior-ischial tuberosity, obturator internus-obturator foramen, obturator externus-obturator foramen, quadratus femoris-ischial tuberosity
- Insertion-piriformis, gemellus superior, obturator internus, gemellus inferior-greater trochanter of femur, obturator externus-trochanteric fossa of femur, quadratus femoris-quadrate tubercle of femur
- Actions-hip ER
-
Pectineus
- Origin-superior ramus of anterior pubis
- Insertion- pectineal line of femur, inferior to lesser trochanter
- Actions-hip flexion, hip add, assists hip IR
-
Adductor Longus
- Origin-anterior pubis-body, inferior to pubic crest
- Insertion-linea aspera of femur-middle 1/3
- Actions-hip add, assists hip flexion
-
Adductor Brevis
- Origin-anterior pubis-body and inferior ramus
- Insertion-linea aspera of femur-proximal part, pectineal line of femur
- Actions-hip add, assists hip flexion
-
Adductor Magnus
- Origin-anterior head-inferior ramus of pubis, posterior head-ischial tuberosity, ramus of ischium
- Insertion-anterior head-linea aspera of femur, posterior head-adductor tubercle of femur

-
Gracilis
- Origin-inferior ramus of anterior pubis
- Insertion-medial proximal tibia
- Actions-hip add, assists knee flexion, assists tibia IR when knee is flexed
-
Gluteus Maximus
- Origin-posterior sacrum, ilium (via sacrotuberous ligament), posterior (superior) gluteal line of ilium
- Insertion-gluteal tuberosity of femur, iliotibial tract (attaching to lateral condyle of tibia
- Actions-hip extension, hip ER
-
Gluteus Medius
- Origin-iliac crest, ilium-between posterior (superior) and anterior (middle) gluteal lines
- Insertion-greater trochanter of femur
- Actions-hip abd, anterior fibers-hip IR
-
Gluteus Minimus
- Origin-posterior ilium-between anterior (middle) and inferior gluteal lines
- Insertion-anterior surface of greater trochanter of femur
- Actions-hip abd, hip IR
-
Tensor Fascia Latae and ITB (iliotibial band)
- Origin-iliac crest-posterior to anterior superior iliac spine
- Insertion-iliotibial tract (attaches to the lateral condyle of tibia)
- Actions-assists hip flexion, assists hip abd, assists hip IR, assists knee extension, assists stability of extended knee in standing and ambulation
