• Origin and insertion of the M. psoas major?

  • Origin from the T12, L1 til L4 and the disci intervertebales.
  • Insertion on the Trochanter Minor of the Femur

• Origin and insertion of the M. psoas minor?

  • Origin from the T12 and L1 vertebrea.
  • Insertion into the Arcus iliopectineus (Fasia iliaca)

• Origin ans insertion of the M. iliacus?

  • Origin from the Fossa iliaca.
  • Insertion on the Trochanter minor.

• The function of the M. psoas minor?

  • Flexion, abduction, lat.rot. of the hip.
  • Unilateral contraction, bending the trunk laterally, bilateral contraction raising the trunk from supine position.

• Origin and insertion of M. gluteus maximus?

  • origin: Lateral part of the dorsal surface of the Os sacrum, posterior part of the Facies glutea of the Os ilium, Fascia thoracolumbalis and Lig. sacrotuberale.
  • Insertion: Upper fibers-Tractus iliotibialis
                      Lower fibers- Tuberositas glutea
               

• The function of M. gluteus maximus?

  • Extend and ext. rot. of the hip, stabilizes the hip in sagittal and coronal(frontal) plane.
    
  • Upper fibers: abduction
  • Lower fibers: adduction

• Origin and insertion M. gluteus minimus?

  • Origin: Facies glutea of Os ilium
  • Insertion: anterolateral surface of the trochanter major femur.

• Function M. gluteus minimus?

  • entire muscle: abducts hip, stabilizes the pelvis in coronal plane.
    
  • Anterior part: flexion and internal rotation
  • posterior part: extension and external rotation.

• Origin and insertion M. tensor fasciae latae?

  • Origin: Spina iliaca anterior superior.(ASIS)
  • insertion:Tractus iliotibialis

• Function M. tensor fasciae latae?

  • Tenses the Fascia lata
  • HIp joint: abduction, flexion, internal rotation
