Answer 2

• Superficial abductors and extenders:
  
  • gluteus maximus, gluteus medius, gluteus minimus and tensor fascia lata
• Deep lateral rotators:
  
  • quadratus femoris, piriformis, gemellus superior, gemellus inferior and obturator internus.

Answer 7

• Attachment: Ilium - greater trochanter
• Actions: Hip abduction and medial rotation, stabalises pelvis
• Innervation: Superior gluteal
• Blood supply: Superior gluteal

Question 8

Tensor Fascia Lata:

• Attachment:
• Actions: (3)

Answer 8

• Attachment: ASIS - Lateral condyle of tibia (IT tract)
• Actions: Hip adbduction and medial rotation. Knee flexion
• Innervation: Superior gluteal nerve
• Blood supply: Profunda femoris (perforator)

Question 9

Clinical Relevance: What happens if the superior gluteal nerve becomes damage in terms of gait?

Answer 9

• Gluteus minimus and medius paralysed
