Final answer:
Foot eversion with plantarflexion is minimized by gravity. The fibularis brevis and fibularis longus muscles are involved in this movement.
Step-by-step explanation:
Foot eversion with plantarflexion is minimized by gravity. The muscles involved in this movement are the fibularis brevis (peroneus brevis) and fibularis longus (peroneus longus).
These muscles plantar flex the foot at the ankle and evert it at the intertarsal joints. Plantar flexion is the movement of lifting the heel off the ground, while eversion is the movement of turning the bottom of the foot away from the midline.
