Question 19

How are the intrinsic muscles of the foot arranged?

Answer 19

Locate din compartments within the sole, where they are arranged in 3 layers or between the metatarsals (7 interossei -> “4th layer of sole”) -> also 2 dorsal muscles

Question 20

What is the main action of the sole muscles of the foot?

Answer 20

Flexion

Question 21

What is the main action of the interossei of the feet?

Answer 21

Abduction/ adduction of the toes

Answer 24

Lateral to extensor hallucis longus tendon

Question 25

What are the medial and lateral plantar arteries branches of?

Answer 25

Posterior tibial artery

Question 26

What arises from both the deep plantar arch and the arcuate artery?
what do these branch to give?

Answer 26

Metatarsal arteries

Branch to give digital arteries

Question 27

What does the dorsal venous arch give rise to?

Answer 27

Great and small saphenous veins

Question 28

What does the anterior and posterior tibial and fibular veins drain into?

Answer 28

Popliteal vein

Question 29

Motor nerve supply to the intrinsic nerves of the foot?

Answer 29

Tibial nerve to muscles of sole and deep fibular nerve to muscles of the dorsum

Question 30

Sensory nerve supply the sole of the foot?

Answer 30

Mainly tibial nerve to the heel and majority of the sole (via medial and lateral plantar nerves)
Sural nerve to proximal lateral border
Saphenous nerve to proximal medial border

Question 31

Sensory nerve supply to dorsum of foot?

Answer 31

Mainly superficial fibular nerve
Deep fibular nerve supplies the first interdigital cleft
Sural nerve = proximal lateral border
Saphenous nerve = proximal medial border
