3 tibialis posterior belongs to the deep division T

4 flexor digitorum longus belongs to the deep division T

5 peroneus longus belongs to the deep division F

Concerning the deep division of the posterior compartment of the leg:

Peroneus longus is one of the two muscles in the lateral compartment of the leg, not posterior compartment.

1 tibialis posterior F

2 flexor hallucis longus F

3 vastus lateralis F

4 vastus medialis F

5 gastrocnemius T

This muscle is called:

1 tibialis posterior

2 flexor hallucis longus

3 vastus lateralis

4 vastus medialis

5 gastrocnemius

This muscle is called:

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:

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.

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:

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.

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:

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.

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:

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 asthe fibular head and neck.

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

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.
