The fibularis longus, also known as peroneus longus, is a muscle located in the lateral compartment of the lower leg. It originates from the head and upper two-thirds of the fibula and extends down along the outside of the leg. The muscle inserts into the base of the first metatarsal and the medial cuneiform bone of the foot, playing a key role in eversion and plantarflexion of the foot.

What is fibularis?
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.
How does the action of the fibularis longus in humans differ from tha of the fibularis tertius?
Inserts on the dorsum of the fifth metatarsal. When it contracts it dorsiflexes and everts the foot
How many muscles located on the lateral side of one leg?
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.
What muscle helps to support the medial longitudinal arch?
Peroneus (fibularis) longus, Tibialis posterior, Flexor Hallucis longus
Name the muscle group that flexes the lower leg?
The dorsiflexors include the extensorum longus, the tibialis anterior, and the peroneus.
