Peroneus longus muscle

The muscle peroneus longus (also known as fibularis longus) is a superficial muscle in the human leg, and acts to evert and plantar flex the ankle.

It is attached proximally to the head of the fibula[?] and its 'belly' runs down most of this bone.

Peroneus longus becomes a tendon that goes posterially around the lateral malleolus of the ankle[?], then continues under the foot to attach to the 1st metatarsal.

Being a muscle of the lateral compartment of the leg, peroneus longus is innervated by the superficial peroneal nerve[?].
