Plantar fleion is a bending action that elevates the heelh, such as when you stand on your boes Seand in the anatomical position and perform dorsiflexion and plantar Bexion. A wbat joint do these actions ocour the median plane. Perform these actions with your foot At what joints do eversion and inversion occur O During protraction, the mandible moves anteriorly During retraction, the mandible moves posteriorly. Place your index finger on the temporomandibular joint, just anterior to the external acoustic meatus. Protract and retract your mandible, and you will detect movement at the joint. 3 Depression lowers the mandible inferiorly.
