Green dots

Answer 27

O: picture I: picture A: thigh abduction medial rotation (minimus especially) N: superior gluteal n.

Question 29

Gait cycle in humans and muscles that unexpectedly help.

Answer 29

* Medius and minimus prevent dropping during stance phase. relax during swing phase * in apes due to ilac not being on sides so attachment is on back not on sides * can cause wadling or falling forward walking bipedally without proper muscle placement

Question 30

Duchennes Limp or trendelenburg's sign

Answer 30

injury to superior gluteal nerve (can also be injury to muscle) * loses steadying action of medius and minimus * lean toward affected side during stance phase * due to drop to opposite side
