Peroneal brevis function
WebDec 3, 2024 · The main function of fibularis brevis is to evert the foot at the subtalar joint, which helps to restore the foot to its anatomical position after it has been inverted. This is particularly important when running or walking on uneven terrain. WebIn human anatomy, the fibularis brevis (or peroneus brevis) is a muscle that lies underneath the fibularis longus within the lateral compartment of the leg. It acts to tilt the sole of the foot away from the midline of the body (eversion) and to extend the foot downward away from the body at the ankle (plantar flexion).
