Muscles responsible for lateral rotation

Question 12

anterior fibres of gluteus medius and minimus, tensor fascia latae

Answer 12

Muscles responsible for medial rotation

Question 13

What limits extension at the hip joint?

Answer 13

• Joint capsule
• Iliofemoral ligament

These structures become taut during extension to limit further movement
