Question 35

When the knee is in flexion and the hip is in extension, what is the action of the adductor longus ?

Answer 35

Hip FLEXION

Question 36

When the knee and hip are fully flexed what is the action of the adductor longs?

Answer 36

Hip EXTENSION

Question 37

Why doesn't the hip have any purely internal rotators?

Answer 37

The hips natural inclination is to fall into internal rotation so the adductors will primarily pull the leg into IR
