Answer 24

Posterior tilt

Question 25

Muscles of the pes anserine tendon

Answer 25

Sartorius, Gracilis, Semitendinosus

Question 26

Glute maximus actions

Answer 26

Abduct the hip Laterally rotate the hip Extend the hip Lower Fibers: Adduct the hip

Question 27

Actions of gracilis vs adductor group

Answer 27

Gracilis is the only adductor to cross the kneecap so it is the only adductor to: Medially rotate the knee when flexed Flex the knee (Along with the other adductors it is involved in Adduction and Medial rotation of the HIP, but it is not involved in assisting the flexion of the hip)
