1 Muscles that Move the Thigh & Leg

2 2 Flex thigh (hip): 1. Psoas major 2. Iliacus Adductors - first 3 also flex thigh: 1. Pectineus 2. Adductor longus - rotates laterally 3. Adductor magnus 4. Gracilis – flexes knee *Total of 5 anterior muscles that flex thigh. Foreswing of thigh when walking, running. Muscles that move the thigh (hip joint) Muscles are attached to the pelvic girdle and femur. Anterior group muscles:

3 Posterior group muscles: Extend thigh (hip): 1. Gluteus maximus – largest muscle in the body. *Straightens leg at the hip when walking, running climbing; raises body from sitting position. Abduct thigh - and rotate medially: 1. Gluteus medius 2. Tensor fasciae latae – Flexes thigh

5 5 Muscles That Move the Thigh Gluteus medius Gluteus maximus Biceps femoris Iliotibial tract (band) Vastus lateralis Rectus femoris Sartorius Tensor fasciae latae Gluteus minimus Piriformis (a) (b)(c)(d) Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display.

6 6 Muscles That Move the Thigh

7 Muscles that Move the Leg (knee joint): This group connects the tibia or fibula to the femur or pelvic girdle. Flexors: 1. Biceps femoris- rotates leg laterally 2. Semitendinosus- rotates leg medially 3. Semimembranosus- rotates leg medially 4. Sartorius (on the anterior side of the leg) – flexes hip

8 8 An extensor of the knee is the Quadriceps femoris group: (made up of four muscles): 1. Rectus femoris 2.Vastus lateralis 3. Vastus intermedius 4. Vastus medialis
