Superficial gluteal muscles Flashcards
1
Q
Gluteus maximus
A
- Origin: gluteal surface of the ilium (behind posterior gluteal line), posterior border of ilium + adjacent part of the iliac crest + Lateroposterior surface of sacrum + coccyx
- Insertion: Iliotibial tract, gluteal tuberosity of femur
Movements - extension of hip
- lateral rot of hip
- lower fibres: adduct
- upper firbres: abduct
2
Q
Gluteus medius
A
- Origin: gluteal (lateral) surface of the ilium (between anterior + posterior gluteal lines)
- Insertion: superolateral side of the greater trochantor of the femur
Movements - abduction of hip
- can produce a downward tilting of the pelvis = raising pelvis on the opposite side
- medial rot (anterior part)
3
Q
Gluteus minimus
A
- Origin: Gluteal surface of ilium (between anterior + inferior gluteal lines)
- Insertion: Anterior aspect of greater trochanter of femur
Movements - hip abduction
- upper attachment = fixed = anterior fibres medially rotate the femur
4
Q
Tensor fascia lata
A
- Origin: anterior part of the outer lip of the iliac crest b/w + including the iliac tubercle + ASIS
- Insertion: b/w the two layers of the IT tract below level of greater trochanter
Movements - flexion, abduction, med rot. of hip joint
- extends knee
