Common fibular nerve

The peroneal nerve (Latin, " common peroneal nerve", synonym: nerve peron ( a) eus communis) is one of two main branches of the sciatic nerve. The other branch is the posterior tibial nerve. The common fibular nerve pulls the side of the knee, at the fibula head over and sends the cutaneous nerve surae lateralis. At the fibula, it divides into its two main branches:

• Superficial fibular nerve and
• Deep fibular nerve

Deep fibular nerve

The deep fibular nerve ( nerve Syn peron ( a) eus profundus, deep peroneal nerve) supplies the muscles that are closer to the dorsum of the foot to the tibia and the extensors of the toe joints:

• Tibialis anterior
• Extensor digitorum longus
• Extensor digitorum brevis
• Extensor digitorum lateralis ( missing in humans)
• Musculus peroneus tertius
• Musculus extensor hallucis longus
• Musculus extensor hallucis brevis

In dogs and cats it also innervates the musculus peroneus longus and peroneus brevis muscle, which are supplied by the superficial peroneal nerve in humans.

In humans, the nerve supply, the skin between the first and second toe sensitive.

A paralysis of the deep peroneal nerve leads to an extended position in the ankle, the toe and the outer edge of the foot are lowered ( " Pes equinovarus "). In animals, there is a stretching of the ankle and a flexed posture of the toes, causing the foot is placed with your foot (so-called " Überköten "). The important in animal Euro Logie tibial cranial reflex is mediated by the deep peroneal nerve.

Superficial fibular nerve

The superficial fibular nerve ( nerve Syn peron ( a) eus superficial, superficial peroneal nerve) innervation in humans the

• Musculus peroneus longus and the
• Musculus peroneus brevis.

In the domestic mammals it is purely sensory. As in humans, the nerve innervates here circumscribed areas of the skin of the lower leg and the dorsum of the foot.
