Question 21

what position of the foot is most stable?

Answer 21

Answer 24

articulation between talus and Calcaneus

Answer 26

Inversion (Tibial's anterior and posterior) Eversion (fibularis longus and brevis)

Question 27

What are the contents of the Tarsal Tunnel?

Answer 27

Tom: Tibialis Posterior Dick: F Digitorum Longus And: Tibial artery Very: Tibial Vein Nervous= Tibial nerve Harry: F Hallucis Longus

Question 28

what are the pulses of the foot

Answer 28

Posterior tibial artery Dorsalis pedis

Question 29

common fibular nerve

Question 30

What nerve innervates the medial part of the thigh?

Answer 30

Obturator

Question 31

Question 44

In which position is the talo-crural joint least stable. Why?

Answer 44

plantar flexion talus us wedge-shaped and the anterior is wider than the posterior so provides more stability in dorsiflexion and leaves palmar vulnerable.
