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.
Peroneus longus and Peroneus brevis tendons
The two lateral ankle muscles that create plantar flexion and eversion of the foot are the peroneus longus and peroneus brevis.
The peroneal nerve, also known as the common fibular nerve, primarily serves the muscles in the anterior and lateral compartments of the leg. This includes the tibialis anterior, which is responsible for dorsiflexion of the foot, and the peroneus longus and peroneus brevis, which facilitate eversion of the foot. Additionally, it innervates the extensor muscles in the foot, aiding in toe extension.
The Achilles tendon is responsible for connecting the calf muscles to the heel bone, allowing for plantarflexion of the foot (pointing the toes downward). It does not directly control the tilting of the foot upwards and out. Tilting the foot upwards and out is typically controlled by the muscles in the lower leg, such as the tibialis anterior and peroneus longus.
Palmaris longus is a flat muscle in the forearm that is a weak wrist flexor. It is missing in some individuals, making it variable in its presence.
Dorsiflexion of the foot uses four muscles. These are the tibialis anterior, extensor digitorum longus, extensor hallucis longus, and the peroneus tertius. The prime mover is the tibialis anterior.

The peroneus longus and peroneus brevis muscles are synergists for eversion of the foot. They work together to assist in turning the foot outward.

peroneus longus and extensor digitorun longus
there are many muscles in the lower leg including peroneus longus. The peroneus longus is near the kneecap but just about under it
There are quite a few muscles that move your foot. The main movers are the tibialis anterior, the extensor digitorum longus, and the peroneus from the front. And the soleus and gastrocnemius from behind.
