What is the function of Fibularis longus and Fibularis brevis?
There are two muscles in the lateral compartment of the leg; the fibularis longus and brevis (also known as peroneal longus and brevis). The common function of the muscles is eversion – turning the sole of the foot outwards. They are both innervated by the superficial fibular nerve.
What is the meaning of Fibularis brevis?
Fibularis brevis, or peroneus brevis, is a short muscle that together with the fibularis (peroneus) longus comprises the group of the lateral leg muscles. Based on their function, both peroneal muscles belong to a larger group of leg muscles whose common function is to plantarflex the foot (point the toes downward).

What is the fibularis longus attached to?
