Iliospoas
Comprises iliacus and psoas major:
- Iliacus arises from the iliac fossa;
- Psoas major arises from vertebrae T12-L5.
- Together, these muscles insert on the lesser trochanter, and flex the thigh.
Sartorius
- Originates on the anterior superior iliac spine
- Inserts on the proximal anteromedial tibia;
- It flexes and laterally rotates the thigh; flexes and medially rotates the leg.
Quadriceps femoris
Comprises rectus femoris, vastus medialis, vastus lateralis, and vastus intermedius.
– These muscles insert at the patella and tibial tuberosity (via tendon of quadriceps femoris).
– They all extend the leg.
– The anterior inferior iliac spine,
– And the superior rim of the acetabulum
– Rectus femoris flexes the thigh (in addition to extending the leg like the other quadriceps muscles).
– Originates on the intertrochanteric line and linea aspera (of the femur).
– Originates on the intertrochanteric line, linea aspera, greater trochanter, and gluteal tuberosity.
– Originates on the shaft of the proximal femur.
