16
Q

What is the insertion of fibularis brevis?

A

the base of the 5th metatarsal (with fibularis tertius)

17
Q

What is the insertion of fibularis longus?

A

medial cuneiform and the base of the 1st metatarsal (with tibialis anterior) - tendon has to go under the foot and so helps to maintain the arch of the foot

18
Q

What are the parts of the fibular retinaculum?

A

superior and inferior

19
Q

What are the borders of the posterior compartment of the leg?

A

the tibia, the fibula, the interosseus membrane, the posterior intermuscular septa

20
Q

What are the muscles of the deep compartment of the posterior compartment of the leg?

A

tibialis posterior, flexor hallicus longus, flexor digitorum longus

21
Q

What are the muscles of the superficial compartment of the posterior compartment of the leg?

A

gastrocnemius, soleus, popliteus, plantaris

22
Q

What is the origin of gastrocnemius?

A

the condyles of the femur

23
Q

What is the insertion of gastrocnemius?

A

calcaneus (via the achilles tendon)

24
Q

What is the origin of soleus?

A

the soleal line

25
Q

What is the insertion of soleus?

A

calcaneus (via the achilles tendon)

26
Q

What is the origin of plantaris?

A

next to the lateral head of gastrocnemius on the femoral condyle

27
Q

What is the action of tibialis posterior?

A

plantar flexion and inversion

28
Q

What is the order of structures passing behind the flexor retinaculum?

A

from the medial malleolus back - TP, FDL, posterior tibial artery, posterior tibial vein, tibial nerve, FHL

29
Q

What is the insertion of tibialis posterior?

A

medial cuneiform and the base of the 1st metatarsal

30
Q

Why do the tendons of FHL and FDL cross?

A

because they are on the wrong sides of the compartment so the tendons have to cross to reach their site of insertion
