Davis Company PP New York, NY SN 9781719640473 LK fadavisat.mhmedical.com/content.aspx?aid=1196332364 RD 2024/03/28 AB The joints, ligaments, and muscles of the ankle and foot provide stability and mobility in the terminal structures of the lower extremity. When a person stands, the foot bears the weight of the body with minimum muscle energy expenditure. During various functinal activities, the foot becomes pliable or relatively rigid depending on the functional demand. This versatility allows the foot to absorb forces, accommodate to uneven surfaces, and serve as a structural lever to propel the body forward during walking and running.
