Question 1 - foot

The highlighted muscle is

1 Abductor digiti minimi T

2 In the 1st layer of the foot T

3 Flexor digiti minimi F

4 Supplied by the medial plantar nerve F

5 Attached to the cuboid F

This is abductor digiti minimi which attaches to the lateral side of base of proximal phalanx of 5th toe and is supplied by the lateral plantar nerve.

Question 1 - foot

The following structures run deep to the flexor retinaculum of the foot:

1 saphenous nerve

2 tibialis posterior tendon

3 tibialis anterior tendon

4 posterior tibial artery

5 long saphenous vein

Question 2 - foot

The following structures run deep to the flexor retinaculum of the foot:

1 saphenous nerve F

2 tibialis posterior tendon T

3 tibialis anterior tendon F

4 posterior tibial artery T

5 long saphenous vein F

Tibialis anterior is in the anterior compartment of the leg and has no relationship to the flexor retinaculum.The saphenous nerve and long saphenous vein run anterior to the medial malleolus. The flexor retinaculum runs backwards and downwards from its attachment on the medial malleolus. Thus the nerve and vein are considerably anterior to the flexor retinaculum.

Question 2 - foot

Concerning tendo calcaneus

1 it is the largest tendon in the body 2 it receives two muscles, both of which are

innervated by the tibial nerve

3 it is inserted onto the inferior surface of the calcaneus

4 it is separated from the ankle joint by a pad of fat

5 it frequently has a bursa on its posterior surface

Question 3 - foot

Concerning tendo calcaneus

1 it is the largest tendon in the body T

2 it receives two muscles, both of which are innervated by the tibial nerve

T

3 it is inserted onto the inferior surface of the calcaneus

F

4 it is separated from the ankle joint by a pad of fat

T

5 it frequently has a bursa on its posterior surface T

Gastrocnemius and soleus are both innervated by the tibial nerve.Tendo calcaneus is inserted onto the posterior surface of calcaneus, not inferior surface.The fat pad is called Kager’s fat pad in orthopaedic literature.

Question 3 - foot

The highlighted tendon

1 Is supplied by the tibial nerve

2 Is called tibialis anterior

3 Everts the foot

4 Attaches to the talus

5 Is supplied by the deep peroneal nerve

Question 4- foot

The highlighted tendon

1 Is supplied by the tibial nerve T

2 Is called tibialis anterior F

3 Everts the foot F

4 Attaches to the talus F

5 Is supplied by the deep peroneal nerve F

This is the tendon of tibialis posterior which attaches predominantly to the navicular bone. It sends extensions to all the tarsal bones except the talus. It inverts the foot and supports the medial longitudinal arch.

Question 4- foot

Complete transection of the sciatic nerve at the level of the greater sciatic foramen will be followed by:

1 inability to extend the knee

2 failure of active plantar flexion of foot

3 failure of active eversion of the foot

4 anaesthesia over the medial aspect of the leg

5 anaesthesia over the dorsum of foot

Question 5 - foot

Complete transection of the sciatic nerve at the level of the greater sciatic foramen will be followed by:

1 inability to extend the knee F

2 failure of active plantar flexion of foot T

3 failure of active eversion of the foot T

4 anaesthesia over the medial aspect of the leg F

5 anaesthesia over the dorsum of foot T

Quadriceps femoris, the extensor of the knee, is supplied by the femoral nerve, not sciatic nerve.The cutaneous innervation over the medial aspect of the leg is by the saphenous nerve, a branch of the femoral nerve.

Question 5 - foot

Concerning movements of the ankle and foot:

1 tibialis anterior is a dorsiflexor of the ankle joint and invertor of the foot

2 peroneus brevis is a plantar flexor of the ankle joint and invertor of the foot

3 peroneus tertius is a dorsiflexor of the ankle joint and evertor of the foot

4 tibialis posterior is a plantarflexor of the ankle joint and invertor of the foot

5 soleus is a plantarflexor of the ankle joint and invertor of the foot

Question 6 - foot

Concerning movements of the ankle and foot:

1 tibialis anterior is a dorsiflexor of the ankle joint and invertor of the foot

T

2 peroneus brevis is a plantar flexor of the ankle joint and invertor of the foot

F

3 peroneus tertius is a dorsiflexor of the ankle joint and evertor of the foot

T

4 tibialis posterior is a plantarflexor of the ankle joint and invertor of the foot

T

5 soleus is a plantarflexor of the ankle joint and invertor of the foot

F

Peroneus brevis is indeed a weak plantarflexor of the ankle but it is an evertor of the foot.Soleus is a plantar flexor of the ankle joint; however it can neither evert nor invert the foot.

Question 6 - foot

With regard to the highlighted structure

1 These are the tendons of flexor digitorum longus

2 The tendons pass deep to the flexor retinaculum

3 The muscle is supplied by the deep peroneal nerve

4 The muscle attaches to the shaft of the tibia

5 This muscle extends the toes 2-5

Question 7 - foot

With regard to the highlighted structure

1 These are the tendons of flexor digitorum longus

F

2 The tendons pass deep to the flexor retinaculum

F

3 The muscle is supplied by the deep peroneal nerve

T

4 The muscle attaches to the shaft of the tibia

F

5 This muscle extends the toes 2-5 T

These are the tendons of extensor digitorum longus which originates from the shaft of the fibula and passes under the extensor retinaculum to insert onto the extensor expansion of toes 2-5.

Question 7 - foot

The following muscles are part of the 3rd layer of the foot

1 Abductor hallucis longus

2 Flexor digiti minimi
