The fibular muscles, also known as the peroneal muscles, are located on the outer side of the lower leg. They consist of two main muscles: the fibularis longus and the fibularis brevis. These muscles play a crucial role in stabilizing the ankle and foot, helping with movements such as eversion, which is the outward turning of the foot. The fibular muscles originate from the fibula, the smaller of the two bones in the lower leg, and attach to various points on the foot. They assist in maintaining balance and support during activities like walking, running, and jumping, making them essential for lower limb function.
