Leg: Review Questions

1. The skin over the medial malleolus is supplied by which of the following nerves?

Saphenous

Lateral sural

Deep peroneal

Sural

Superficial peroneal

2. Which of the following descriptions of the blood supply to the leg is TRUE?

The posterior tibial artery passes through the interosseous membrane to supply blood to the anterior crural compartment

The peroneal (fibular) artery is located in the posterior crural compartment and it supplies blood to both the posterior and lateral crural compartments

The medial plantar artery is a branch of the posterior tibial artery while the lateral plantar artery is a branch of the deep peroneal artery

The metatarsal branches of the dorsalis pedis artery are the only blood supply to the digits

None of the above is true

3. Which of the following muscles of the lower limb acts across two joints?

Sartorius

Gracilis

Rectus femoris

Gastrocnemius

All of the above

4. When the shaft of the fibula is broken just distal to the neck, which artery is most likely to be injured by the fracture?

Popliteal artery

Anterior tibial artery

Posterior tibial artery

Lateral malleolar artery

5. The fibula:

Functions primarily in weight bearing

Articulates with the lateral condyle of the tibia by way of a syndesmosis

Provides an insertion site for the biceps femoris muscle

Articulates directly with the navicular bone

Provides an attachment site for the deltoid ligament

6. The lateral compartment of the leg:

Contains muscles that are supplied by the deep peroneal nerve

Contains muscles that function primarily to invert the foot

Is separated from the anterior compartment by the interosseous membrane of the leg

Is separated from the posterior compartment by the posterior intermuscular septum

Contains the anterior tibial artery

7. The posterior tibial artery:

Descends in the leg directly adjacent to the deep peroneal nerve

Descends in the leg anterior to the transverse intermuscular septum

Gives rise to the dorsalis pedis artery

Is located lateral to the calcaneal tendon at the level of the ankle

Descends in the leg between the gastocnemius and soleus muscles

8. The deep peroneal nerve:

Supplies the motor innervation to the peroneus longus muscle

Is located superficial to the superior extensor retinaculum

Supplies muscles that dorsiflex the foot

Is the motor nerve of the lateral compartment of the leg

Both A and C are true

9. The gastrocnemius muscle:

Can act to flex the leg at the knee joint

Is supplied by the superficial peroneal nerve

Is located anterior to the soleus muscle

Is located in the anterior compartment of the leg

Can act to dorsiflex the foot at the ankle joint
