Each foot is made up of 28 bones, 30 joints, and more than 100 muscles, tendons, and ligaments, all of which work together to provide support, balance, and mobility. Nearly one-fourth of the body's bones are in the feet. They are divided into three parts: the hindfoot, midfoot, and forefoot.
Joints in the feet are where two or more bones meet. Joints In the feet are covered with cartilage in order to glide smoothly against one another as they move. Twenty muscles give the foot its shape, support, and the ability to move. Tendons attach muscles to bones. Ligaments hold bones together to maintain the foot's arch. The main tendon, the Achilles tendon, runs from the calf muscle to the heel and makes it possible to run, jump, and climb stairs.
