Plantar flexion
Plantiflexio
- Synonym: Plantiflexion
Definition
Plantar flexion occurs at the ankle joint and involves the sole of the foot moving downwards towards the floor. It is in fact, the flexion movement at the ankle joint. Daily life activities involving plantar flexion at the ankle joint include pressing the peddle of the car for escalating or breaking, standing on tippy toes (such as, in ballet dancing) and jumping off the floor.
Plantar flexion is brought about by the combined action of flexor muscles in the back of the leg (gastrocnemius, soleus, plantaris, flexor hallucis longus, flexor digitorum longus and flexor hallucis longus) and by the peroneal compartment muscles, namely the peroneus longus and brevis muscles.
