What bones are used in the plantar flexion movement?

Plantar flexion primarily involves the bones of the lower leg and foot, particularly the tibia and fibula in the leg, as well as the bones of the foot, including the talus, calcaneus, and metatarsals. During this movement, the ankle joint, formed by the tibia and fibula with the talus, allows the foot to point downward. The action is mainly facilitated by the gastrocnemius and soleus muscles, which attach to the heel bone (calcaneus) via the Achilles tendon.
