fibularis longus in dogs

A superficial muscle in the lateral compartment of the leg, and acts to evert and plantar flex the ankle. It is situated at the upper part of the lateral side of the leg, and is the most superficial of the three peroneus muscles. It is innervated by the superficial fibular nerve (superficial peroneal nerve). [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.
