Fibularis Longus is a muscle on the lateral side of the leg. It originates from the upper 3rd of the fibula and inserts onto the base of the first metatarsal in the foot. Its main functions are powerful eversion of the foot and plantarflexion. Additionally Fibularis Longus is innervated by the tibial nerve.
Inserts on the dorsum of the fifth metatarsal. When it contracts it dorsiflexes and everts the foot
On the lateral side of one leg, there are primarily three muscles: the fibularis longus, the fibularis brevis, and the fibularis tertius. The fibularis longus and brevis are responsible for eversion of the foot, while the fibularis tertius assists in dorsiflexion and eversion. These muscles play a crucial role in stabilizing the ankle and supporting movements during walking and running.
Peroneus (fibularis) longus, Tibialis posterior, Flexor Hallucis longus
The dorsiflexors include the extensorum longus, the tibialis anterior, and the peroneus.
In human anatomy, the fibularis longus (also known as peroneus longus) is a superficial muscle in the lateral compartment of the leg, and acts to evert and plantar flex the ankle.
