I: the fibres pass upwards, backwards and laterally to attach to the posterior part of the medial surface of the lateral femoral condyle
AUBL (Anterior, Upwards, Backwards, Laterally)

I: the fibres pass upwards, forwards & medially to attach to the lateral surface of the medial condyle of the femur.
PUFM (Posterior, Upwards, Forwards, Medially)

Answer 4

O: Lateral epicondyle of the femur
I: head of the fibula (lateral surface)
Limitation: limits varus forces of the knee

Question 5
