Anatomy & Physiology: Muscles—Fibularis (Peroneus) Tertius.
Structure.
- Origin: distal third of fibula and interosseous membrane.
- Insertion: base of metatarsal V.
Function.
- Concentric action: dorsiflexion; eversion at intertarsal joints.
- Reverse mover action: dorsiflexion and eversion (at talus).
- Eccentric action: controls/restrains/decelerates ankle plantarflexion, supination at subtalar joint.
- Isometric action: stabilize ankle and subtalar joints.
- Innervation: deep fibular (peroneal) nerve.
- Arterial supply: anterior tibial artery.
