Origin: Iliac Fossa of Ilium (11) 
Insertion: Lesser Trochanter of femur (10), in front of the Psoas Major (1) fibers
Actions:
- during unilateral contraction it Flexes the thigh at the hip joint
- during bilateral contraction it Flexes the trunk
Helping Synergist Muscles:
- together with Psoas Major, Sartorius, Rectus Femoris, Tensor Fasciae Latae, Pectineus (2), Adductor Major (7), Adductor Longus (3) acts the thigh Flexion
- together with Gluteus Maximus, Gluteus Medius, Rectus Femoris, Adductor Maximus and Adductor Brevis (6) helps the External Rotation of the thigh
Notes: together with the Psoas Major it forms the Ileopsoas muscle, a large, broad and convergent type of skeletal muscle
