  1. PowerPoint® Lecture Slides prepared by Janice Meeking, Mount Royal College CHAPTER 10 The Muscular System: Part D Copyright © 2010 Pearson Education, Inc.
  2. Muscles Crossing Hip and Knee Joints • Most anterior muscles flex the femur at the hip and extend the leg at the knee (foreswing of walking) • Most posterior muscles extend the thigh and flex the leg (backswing of walking) • Medial muscles all adduct the thigh • All three groups are enclosed by the fascia lata PLAY A&P Flix™: Muscles that act on the hip joint and femur: An overview Copyright © 2010 Pearson Education, Inc.
  3. Movements of the Thigh • Include flexion, extension, abduction, adduction, circumduction, and rotation • Thigh flexors pass in front of the hip joint • Iliopsoas (iliacus and psoas major): prime mover of flexion • Tensor fasciae latae • Rectus femoris • Assisted by medial adductors and sartorius PLAY A&P Flix™: Anterior muscles that cross the hip joint Copyright © 2010 Pearson Education, Inc.
  4. 12th rib 12th thoracic vertebra Quadratus lumborum Psoas minor Iliac crest Psoas major Iliopsoas Iliacus 5th lumbar vertebra Anterior superior iliac spine Tensor fasciae latae Pectineus Sartorius Adductor longus Gracilis Quadriceps femoris Adductor magnus • Rectus femoris • Vastus lateralis • Vastus medialis Tendon of quadriceps femoris Patella Patellar ligament (a) Copyright © 2010 Pearson Education, Inc. Figure 10.19a
  5. Movements of the Thigh PLAY A&P Flix™: Iliopsoas PLAY A&P Flix™: Tensor fasciae latae PLAY A&P Flix™: Rectus femoris PLAY A&P Flix™: Sartorius Copyright © 2010 Pearson Education, Inc.
  6. Movements of the Thigh • Thigh extensors • Hamstring muscles (prime movers of extension) • Biceps femoris • Semitendinosus • Semimembranosus • Gluteus maximus (prime mover during forceful extension) Copyright © 2010 Pearson Education, Inc.
  7. Gluteus medius Gluteus maximus Adductor magnus Gracilis Iliotibial tract Long head Biceps Short head femoris Hamstrings Semitendinosus Semimembranosus (a) Copyright © 2010 Pearson Education, Inc. Figure 10.20a
  8. Movements of the Thigh PLAY A&P Flix™: Biceps femoris PLAY A&P Flix™: Semitendinosus PLAY A&P Flix™: Semimembranosus Copyright © 2010 Pearson Education, Inc.
  9. Movements of the Thigh • Adductors (also medially rotate thigh) • Adductor magnus • Adductor longus • Adductor brevis • Pectineus • Gracilis PLAY A&P Flix™: Medial muscles that cross the hip joint Copyright © 2010 Pearson Education, Inc.
  10. Pectineus (cut) Adductor brevis Adductor magnus Adductor longus Femur O = origin I = insertion (b) PLAY A&P Flix™: Pectineus Copyright © 2010 Pearson Education, Inc. Figure 10.19b
  11. Movements of the Thigh • Abductors • Gluteus maximus (also laterally rotates thigh) • Gluteus medius (also medially rotates thigh) • Gluteus minimus (also medially rotates thigh) • Piriformis (also laterally rotates thigh) • Obturator externus (also laterally rotates thigh) • Obturator internus (also laterally rotates thigh) • Gemellus (also laterally rotates thigh) PLAY A&P Flix™: Posterior muscles that cross the hip joint Copyright © 2010 Pearson Education, Inc.
  12. Gluteus medius (cut) Gluteus minimus Superior gemellus Piriformis Obturator Obturator internus externus Inferior Quadratus gemellus femoris Gluteus maximus (cut) (c) Copyright © 2010 Pearson Education, Inc. Figure 10.20c
  13. Movements of the Thigh PLAY A&P Flix™: Gluteus maximus(c) PLAY A&P Flix™: Gluteus medius Copyright © 2010 Pearson Education, Inc.
  14. Summary of Movement at the Hip Joint PLAY A&P Flix™: Movement at the hip joint Copyright © 2010 Pearson Education, Inc.
  15. Muscles of the Thigh that Move the Knee Joint • Quadriceps femoris—sole extensor of the knee • Hamstring muscles—flex the knee, and are antagonists to the quadriceps femoris PLAY A&P Flix™: Muscles that cross the knee joint: An overview. Copyright © 2010 Pearson Education, Inc.
  16. 12th rib 12th thoracic vertebra Quadratus lumborum Psoas minor Iliac crest Psoas major Iliopsoas Iliacus 5th lumbar vertebra Anterior superior iliac spine Tensor fasciae latae Pectineus Sartorius Adductor longus Gracilis Quadriceps femoris Adductor magnus • Rectus femoris • Vastus lateralis • Vastus medialis Tendon of quadriceps femoris Patella Patellar ligament (a) PLAY A&P Flix™: Movement at the hip joint Copyright © 2010 Pearson Education, Inc. Figure 10.19a
  17. Muscles of the Thigh that Move the Knee Joint PLAY A&P Flix™: Anterior extensors that act on the knee PLAY A&P Flix™: Rectus femoris PLAY A&P Flix™: Vastus lateralis PLAY A&P Flix™: Vastus medialis PLAY A&P Flix™: Vastus intermedius Copyright © 2010 Pearson Education, Inc.
  18. Gluteus medius Gluteus maximus Adductor magnus Gracilis Iliotibial tract Long head Biceps Short head femoris Hamstrings Semitendinosus Semimembranosus (a) PLAY A&P Flix™: Movement at the hip joint Copyright © 2010 Pearson Education, Inc. Figure 10.20a
  19. Muscles of the Thigh that Move the Knee Joint PLAY A&P Flix™: Posterior flexors that act on the knee PLAY A&P Flix™: Biceps femoris PLAY A&P Flix™: Semitendinosus PLAY A&P Flix™: Semimembranosus Copyright © 2010 Pearson Education, Inc.
