1

Describe the route of the small saphenous vein

Starts just posterior to the lateral ankle (malleolus)
Runs up the centre of the posterior leg
Enters popliteal region to drain into popliteal vein

2

How many muscles reside in the posterior leg?

7

3

Which nerve roots does the calcaneal reflex test?

S1-S2

4

Name the 2 bursae associated with the calcaneal tendon

Subcutaneous calcaneal bursa
Deep bursa of calcaneal tendon

5

What is the origin of gastrocnemius?

Medial head = medial femoral condyle
Lateral head = lateral femoral condyle

6

What is the insertion of the gastrocnemius?

Calcaneus

7

What are the actions of the gastrocnemius?

Plantarflexion of foot
Flexor of knee

8

What is the nerve supply to gastrocnemius?

Tibial nerve

9

What is the nerve supply to all superficial posterior leg muscles?

Tibial nerve

10

What are the superficial posterior leg muscles?

Gastrocnemius
Plantaris
Soleus

11

What is the origin of plantaris?

Lateral supracondylar line of femur

12

What is the insertion of plantaris?

Calcaneus

13

What are the actions of plantaris?

Plantarflexion of foot
Flexion of knee

14

What is the nerve supply to plantaris?

Tibial nerve

15

What is the origin of soleus?

Soleal line of tibia

16

What is the insertion of soleus?

Calcaneus

17

What is the action of soleus?

Plantarflexion

18

What is the nerve supply to soleus?

Tibial nerve

19

Describe a ruptured calcaneal tendon

Usually occurs through forceful plantarflexion
Foot will be permanently dorsiflexed
Soleus and gastrocnemius contract to form a lump in the calf

20

How many deep muscles of the posterior leg are there?

4

21

What is the origin of popliteus?

Posterior, proximal tibia

22

What is the insertion of popliteus?

Lateral condyle of femur

23

What is the action of the popliteus?

'Unlocking' the knee - laterally rotate femur on tibia

24

What is the nerve supply to popliteus?

Tibial nerve

25

What is the origin of tibialis posterior?

Interosseous membrane of tibia and fibula and the posterior surfaces of these 2 bones

26

What is the insertion of tibialis posterior?

Plantar surface of medial tarsal bones

27

What are the actions of TP?

Inverts and plantarflexes the foot
Maintains medial arch of foot

28

What is the nerve supply to TP?

Tibial nerve

29

What is the origin of FDL?

Medial surface of tibia

30

What is the insertion of FDL?

Plantar surfaces of lateral 4 toes
