Where are the fibularis longus?

The fibularis longus, also known as peroneus longus, is a muscle located in the lateral compartment of the lower leg. It originates from the head and upper two-thirds of the fibula and extends down along the outside of the leg. The muscle inserts into the base of the first metatarsal and the medial cuneiform bone of the foot, playing a key role in eversion and plantarflexion of the foot.
