Question 6

Answer 6

Patellar ligament

Question 7

What is the iliotibial tract?

Answer 7

Longitudinal fibrous band reinforcement of the fascia lata.

Extends, abducts and laterally rotates hips.

Lateral knee stabilization.

Question 8

Which bone of the foot articulates with the tibia?

Answer 8

Talus

Question 9

What is the function of the interosseous membrane?

Answer 9

Stabilizes the tibiofibular positioning.

Separates anterior and posterior muscles.

Question 10

Why do fractures of the tibia often result in fractures of the fibula?

Answer 10

The interosseous membrane is so strong that a fracture in the tibia will often pull on the fibula via the membrane - causing it to fracture as well
