compartment.

10. 1 tibialis posterior F
2 flexor hallucis longus F
3 vastus lateralis F
4 vastus medialis F
5 gastrocnemius T
This muscle is called:

11. 1 tibialis posterior
2 flexor hallucis longus
3 vastus lateralis
4 vastus medialis
5 gastrocnemius
This muscle is called:

12. 1 it belongs to the superficial division of the posterior compartment of
the leg
2 it arises from the lateral supracondylar ridge of the femur
3 it inserts onto the posterior surface of the talus
4 it plantar-flexes the ankle and flexes the knee
5 it dorsiflexes the foot
Concerning Plantaris:

13. 1 it belongs to the superficial division of the posterior compartment of
the leg
T
2 it arises from the lateral supracondylar ridge of the femur T
3 it inserts onto the posterior surface of the talus F
4 it plantar-flexes the ankle and flexes the knee T
5 it dorsiflexes the foot F
Concerning Plantaris:
The distal attachment (ie; insertion) of the plantaris tendon is to the calcaneus alongside the
insertion of tendo-calcaneus.
Plantaris is a very weak flexor of the knee and weak plantar flexor of the ankle.

14. 1 belongs to the deep group of flexor muscles in the leg
2 is innervated by the deep peroneal nerve
3 is an invertor of the foot
4 is attached distally to the base on the 5th metatarsal
5 is attached to the navicular tuberosity
The tibialis posterior muscle:

15. 1 belongs to the deep group of flexor muscles in the leg T
2 is innervated by the deep peroneal nerve F
3 is an invertor of the foot T
4 is attached distally to the base on the 5th metatarsal F
5 is attached to the navicular tuberosity T
The tibialis posterior muscle:
The tibial nerve, not the deep peroneal nerve, innervates tibialis posterior
Tibialis posterior is attached distally to the tuberosity of the navicular.

16. 1 arises from the posterior aspect of the proximal fibula
2 lies deep to the gastrocnemius
3 is innervated by the common peroneal nerve
4 is a plantar-flexor of the ankle joint
5 is a weak flexor of the knee joint
The soleus muscle:

17. 1 arises from the posterior aspect of the proximal fibula T
2 lies deep to the gastrocnemius T
3 is innervated by the common peroneal nerve F
4 is a plantar-flexor of the ankle joint T
5 is a weak flexor of the knee joint F
The soleus muscle:
The Soleus muscle belongs to the superficial group of posterior
compartment muscles in the leg. Like ALL the muscles in the posterior
compartment of the leg it is innervated by the tibial nerve, not common
peroneal nerve.
It is a powerful plantar-flexor of the ankle. However it has no action on the
knee joint, being entirely distal to the knee joint.

18. 1 arises from the proximal 1/4th of the posterior surface of the
tibia
2 arises from the posterior surface of the head and neck of
fibula
3 derives its motor innervation from the tibial nerve
4 lies medial to the tendon of tibialis posterior in the tarsal
tunnel
5 grooves the back of the talus on its way to the sole of the foot
The flexor hallucis longus:

19. 1 arises from the proximal 1/4th of the posterior surface of the
tibia
F
2 arises from the posterior surface of the head and neck of
fibula
F
3 derives its motor innervation from the tibial nerve T
4 lies medial to the tendon of tibialis posterior in the tarsal
tunnel
F
5 grooves the back of the talus on its way to the sole of the foot T
The flexor hallucis longus:
Flexor hallucis longus belongs to the deep group of muscles in the
posterior compartment of the leg. It is innervated by the tibial nerve.
It arises from the posterior surface of the fibula but not as high as
the fibular head and neck.

20. 1 the posterior tibial artery pierces the tibio-fibular interosseous
membrane to enter the posterior compartment of the leg
2 the posterior tibial artery is usually the smaller of the two
terminal branches of the popliteal artery
3 the posterior tibial artery ends in the distal part of the leg by
dividing into the dorsalis pedis and peroneal arteries
4 the posterior tibial artery gives off the peroneal artery as a
direct branch
5 the posterior tibial artery is accompanied by venae
commitantes

compartment of the leg:

Concerning the vascular arrangement in the posterior
compartment of the leg:
The posterior tibial artery is the larger of the two terminal branches of the popliteal
artery. It originates in the posterior compartment of the leg and therefore does not
have to pierce the interosseous membrane to reach the posterior compartment.
The peroneal artery is a direct and early branch of the posterior tibial.
The posterior tibial artery is always accompanied by large venae commitantes, and
ends by dividing into medial and lateral plantar arteries.
