Action

Foot evertors
Foot plantarflexion

Nerve supply

The lateral compartment of the leg is supplied by the superficial fibular nerve (superficial peroneal nerve).

Blood supply

Its proximal and distal arterial supply consists of perforating branches of the anterior tibial artery and fibular artery.{{cite journal |last1=Khan |first1=Irfan A. |last2=Mahabadi |first2=Navid |last3=D’Abarno |first3=Anthony |last4=Varacallo |first4=Matthew |title=Anatomy, Bony Pelvis and Lower Limb, Leg Lateral Compartment |journal=StatPearls |date=2020 |url=https://www.ncbi.nlm.nih.gov/books/NBK519526/#:~:text=The%20function%20of%20the%20superficial,to%20the%20lateral%20leg%20compartment |accessdate=20 October 2020 |publisher=StatPearls Publishing|pmid=30137811 }}
