Transcript

  • 1. Gluteal Region Anatomy
    By:
    Mohammed Faez
  • 2. Muscles of the Gluteal Region
    The muscles of the gluteal region are responsible for extension, abduction, lateral rotation and slight medial rotation of the hip joint.
  • 3. Muscles of the Gluteal Region
    Starting from superficial and going deep identify the following muscles:
    Gluteus maximus
    Gluteus medius
    Gluteus minimus
    Piriformis
    Superior gemellus
    Obturatorinternus
    Inferior gemellus
    Obturatorexternus
    Quadratusfemoris
  • 4. Muscles of the Gluteal Region
    The tensor fascia latae is seen from the lateral side of the gluteal region
  • 5. Arteries of the Gluteal Region
    Superior gluteal
    Inferior gluteal
    Internal pudendal
    These arteries are branches of the internal iliac artery which lies inside the pelvis.
    There are three arteries coming into the gluteal region through the greater sciatic foramen.
  • 6. Nerves of the Gluteal Region
    The nerves of the gluteal region are branches of the lumbosacral plexus:
    Superior gluteal N
    Inferior gluteal N
    Sciatic N
    Posterior femoral cutaneous N
    PudendalN
  • 7. Gluteal Region Muscles
    Gluteus Maximus
    Origin: iliac crest, sacrum
    Insertion: iliotibial tract, lineaaspera
    Action: extension of thigh at hip and lateral rotation of thigh
    Innervation: Inferior gluteal nerve
  • 8. Gluteal Region Muscles
    Gluteus Medius
    Origin: iliac crest
    Insertion: Greater trochanter
    Action: Abduction and medial rotation of thigh at the hip
    Innervation: Superior gluteal nerve
  • 9. Gluteal Region Muscles
    Gluteus Minimus
    Origin: Lateral surface of ilium
    Insertion: Greater trochanter
    Action: Abduction, medial rotation at hip
    Innervation: Superior gluteal nerve
  • 10. Gluteal Region Muscles
  • 11. Gluteal Region Muscles
    Tensor Fascia Latae
    Origin: iliac crest
    Insertion: iliotibial tract
    Action: assists gluteus maximus inextending the knee joint
    Innervation: superior gluteal nerve
    The tensor fascia latae is seen from the lateral side of the gluteal region
  • 12. Gluteal Region Muscles
    Deep to gluteus maximus are a number of small rotator muscles of the hip, including:
    Piriformis
    Gemelli muscles (superior – inferior )
    Obturatorinternus
    Obturatorexternus
    Quadratusfemoris
  • 13. Gluteal Region Muscles
    Piriformis
    Origin: Anterior surface of sacrum
    Insertion: greater trochanter
    Action: lateral rotation of thigh (at hip joint); abduction of flexed thigh
    Innervation: Sacral nerve S1 and S2
  • 14. Gluteal Region Muscles
    Superior Gemellus
    Origin: ischial spine
    Insertion: greater trochanter of femor
    Action: lateral rotation of femur
    Innervation: Sacral plexus
  • 15. Gluteal Region Muscles
    Inferior Gemellus
    Origin:Ischialtuberosity
    Insertion: Greater trochanter of femur
    Action: lateral rotation of femur
    Innervation: Sacral plexus
  • 16. Gluteal Region Muscles
    ObturatorInternus
    Origin: internal aspect of obturator foramen & obturator membrane
    Insertion: greater trochanter
    Action: lateral rotation of femur; abduction of thigh when hip is flexed
    Innervation: Sacral plexus
  • 17. Gluteal Region Muscles
    ObturatorExternus
    Origin: obturator foramen & obturator membrane (external surface)
    Insertion: Greater trochanger of femur
    Action: lateral rotation of thigh (at hip joint); adduction of thigh (weak)
    Innervation: obturator nerve
  • 18. Gluteal Region Muscles
    QuadratusFemoris
    Origin: ischialtuberosity
    Insertion: intertrochanteric crest of femur
    Action: lateral rotation of thigh (at hip joint); adduction of thigh (weak)
    Innervation:Sacral plexus
