1

What is the arrangement of structures that pass under the medial malleolus?

Tom Dick And Very Naughty Harry

Tibialis posterior

Flexor Digitorum Longus

Artery

Vein

Nerve

Flexor Hallicus Longus

2

What is another name for the achilles tendon?

Tendo-calcaneus

3

What movement does contraction of tibialis anterior cause?

Dorsiflexion

Inversion

3

Where does tibialis anterior insert?

The base of the 1st metatarsal and medial cuneiform

4

Why does the tendon of FHL have to pass under the tendon of FDL?

Because its muscle body is lateral on the leg but it inserts onto the medially located great toe

5

What is the origin of the gastrocnemius?

One on each condyle of the femur - to allow for both of the gastrocnemius bellies

6

Describe the origin of the soleus muscle?

Runs obliquely down the fibula and tibia with an arch for vessels to pass through

8

What are the muscles of the anterior compartment of the leg?

Tibialis anterior 

Extensor digitorum longus

Extensor hallucis longus

9

What is the insertion of tibialis posterior?

Base of 1st metatarsal

Medial cuneiform

10

Which surface of the tibia is its most common site of compound fractures?

The medial surface

10

What is the pattern of insertion of the tendons of EDL?

They insert into the lateral 4th toes

Each tendon splits into 3

11

What important physiological role does the soleus have?

Pump blood back up the legs

12

What are the muscles of the lateral compartment of the leg?

Fibularis longus

Fibularis brevis

13

Which muscle's tendon grooves the lateral malleolus?

Fibularis brevis

 

14

What are the superficial muscles of posterior compartment of the legs called?

Gastrocnemius

Soleus

Popliteus

Plantaris

15

What is the major role of the popliteus?

Forms the floor of the popliteal fossa

 

16

What movement do the muscles of the lateral compartment facilitate?

Eversion

17

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

Flexor digitorum longus

Tibialis posterior

Flexor hallicus longus

18

From which muscles does the fibularis tertius branch off?

Extensor digitorum longus

20

Compare the insertion points of fibularis longus and brevis?

Longus inserts into the base of 1st metatarsal, near tibialis anterior

While brevis inserts into the 5th metatarsal

21

Contraction of tibialis posterior cause what movement?

Inversion and plantarflexion
