Branches
Previous to its division it gives off articular and lateral sural cutaneous nerves.
- The articular branches (rami articulares) are three in number:
- Two of these accompany the superior and inferior lateral genicular arteries to the knee; the upper one occasionally arises from the trunk of the sciatic nerve.
- The third (recurrent) articular nerve is given off at the point of division of the common fibular nerve; it ascends with the anterior recurrent tibial artery through the tibialis anterior to the front of the knee.
- The lateral sural cutaneous nerve (n. cutaneus suræ lateralis; lateral cutaneous branch) supplies the skin on the posterior and lateral surfaces of the leg.
- The motor branches:
- As the common fibular nerve exits the popliteal fossa, it courses around the lateral aspect of the leg just below the head of the fibula. Here it is apposed with fibula and gives off two branches, the superficial fibular (peroneal) branch and deep fibular (peroneal) branch.
- The superficial peroneal nerve supplies the muscles of the lateral compartment of the leg namely: peroneus longus and peroneus brevis. These two muscle help in eversion and plantar flexion of the foot.
- The deep peroneal nerve innervates the muscles of the anterior compartment of the leg which are: tibialis anterior, extensor hallucis longus, extensor digitorum longus, and the fibularis (peroneus) tertius. Together these muscles are responsible for dorsiflexion of the foot and extension of the toes.

“I couldnt afford to learn it, said the Mock Turtle with a sigh. I only took the regular course.
What was that? inquired Alice.

I never heard of Uglification, Alice ventured to say.”

“It is comforting when one has a sorrow to lie in the warmth of ones bed and there, abandoning all effort and all resistance, to bury even ones head under the cover, giving ones self up to it completely, moaning like branches in the autumn wind. But there is still a better bed, full of divine odors. It is our sweet, our profound, our impenetrable friendship.”
—Marcel Proust (18711922)
