Common peroneal nerve

Question 2

Describe the course of the common fibular nerve.

Answer 2

The common fibular nerve arisese a the apex of the polpiteal fossa.

It follows the medial border of the biceps femoris, running in an inferolateral direction, over the lateral head of the gastrocnemius. At this point, the common fibular nerve gives rise to two cutaneous branches, which contribute to the innervation of the skin of the leg.

To enter the lateral compartment of the leg, the nerve wraps around the neck of the fibula, passing between the attachments of the fibularis longus muscle. Here, the common fibular nerve terminates by dividing into the superficial fibular and deep fibular nerves.
