Answer 8

iliopsoas

Question 9

tensor fasciae latel (TFL)

Answer 9

origin:

Question 10

iliotibial tract (IT band)

Answer 10

• a band of thickened fascia that runs along the lateral thigh
• attached to gerdy’s tubercle

Answer 13

origin:
- lateral ilium
insertion:
- greater trochanter
innervation:
- lumbosacral plexus
function:
- hip extension
- hip abduction
