Question 2

Sacrospinous

Answer 2

attachments- from the ischial spine to lateral margin of the sacrum

Question 3

Fibrous joint capsule

Answer 3

attachments- from the margin of the acetabulum to the neck, intertrochanteric line & intertrochanteric crest of the femur

Question 4

Iliofemoral

Answer 4

attachments- from the AIIS to the intertrochanteric line of the femur
