Structure.
- Origin: fibular head and body; lateral condyle of tibia.
- Insertion: metatarsal I and first cuneiform.
Function.
- Concentric action: plantar flexion; eversion.
- Reverse mover action: evert talus at subtalar joint; plantar flexion.
- Eccentric action: decelerates ankle dorsiflexion and inversion.
- Isometric action: stabilization of foot and ankle.
