Related to peroneus: Peroneus tertius


(pĕr″ō-nē′ŭs) [Gr. perone, pin]
One of three muscles of the leg that act to move the foot.

peroneus brevis

The muscle arising from the distal two thirds of the lateral fibula and attaching to the styloid process of the base of the fifth metatarsal. The peroneus brevis assists in plantar flexion of the foot and eversion of the ankle.

peroneus longus

The muscle arising from the lateral tibial condyle and the upper two thirds of the fibula and inserting on the lateral aspect of the first metatarsal and the associated portion of the first cuneiform. The peroneus longus is the primary contributor to the plantar flexion of the foot and the eversion of the ankle.

peroneus tertius

The muscle arising from the anterior portion of the distal one third of the tibia and the adjacent portion of the interosseous membrane and attaching on the dorsal surface of the fifth metatarsal. The peroneus tertius is a secondary contributor to ankle dorsiflexion and eversion. This muscle is absent in a significant proportion of the population.

Any one of the muscles that take origin from the FIBULA and are inserted into the bones of the foot. The peroneal muscles assist in walking and in everting the raised foot.
