Corpus: Superficial fibular nerve

The superficial fibular nerve is a branch of the common fibular nerve with both motor and sensory functions.

Originating at the bifurcation of the common fibular nerve, the superficial fibular nerve runs between the fibula and the fibularis longus muscle. It continues caudally between the fibular muscles and the extensor digitorum longus muscle, eventually piercing the lower leg's fascia cruris in its distal third. Shortly thereafter, it splits into two sensory branches: the medial dorsal cutaneous nerve and the intermediate dorsal cutaneous nerve. These branches further divide into their terminal branches, known as the digital dorsal pedal nerves.

The superficial fibular nerve innervates the following muscles:

• fibularis longus muscle
• fibularis brevis muscle

It also provides sensory innervation to most of the skin on the dorsal aspect of the foot. A small area on the lateral side of the foot's dorsum is innervated by the sural nerve. The area between the first and second toes receives innervation from the deep fibular nerve.
