Peroneal Nerves
The common fibular nerve (also known as the common peroneal nerve, external popliteal nerve, or lateral popliteal nerve) is a nerve in the lower leg that provides sensation over the wikt:posterolateral, posterolateral part of the leg and the knee joint. It divides at the knee into two terminal branches: the superficial fibular nerve and deep fibular nerve, which innervate the muscles of the lateral and anterior compartments of the leg respectively. When the common fibular nerve is damaged or Nerve compression syndrome, compressed, foot drop can ensue. Structure The common fibular nerve is the smaller terminal branch of the sciatic nerve. The common fibular nerve has root values of L4, L5, S1, and S2. It arises from the superior angle of the popliteal fossa and extends to the lateral angle of the popliteal fossa, along the medial border of the biceps femoris. It then winds around the neck of the fibula to pierce the fibularis longus and divides into terminal branches of the superfi ...

Anterior Compartment Of Leg
The anterior compartment of the leg is a fascial compartment of the lower leg. It contains muscles that produce dorsiflexion and participate in inversion and eversion of the foot, as well as vascular and nervous elements, including the anterior tibial artery and veins and the deep fibular nerve. Muscles The muscles of the compartment are: * tibialis anterior * extensor hallucis longus * extensor digitorum longus * fibularis (peroneus) tertius Function The compartment contains muscles that are dorsiflexors and participate in inversion and eversion of the foot. Innervation and blood supply The anterior compartment of the leg is supplied by the deep fibular nerve (deep peroneal nerve), a branch of the common fibular nerve. The nerve contains axons from the L4, L5, and S1 spinal nerves. Blood for the compartment is supplied by the anterior tibial artery, which runs between the tibialis anterior and extensor digitorum longus muscles. When the artery crosses the exte ...
