What Bones are in my Hands and Feet?
The Phalanges-The phalanges are the small bones that make up the skeleton of the fingers, thumb and toes. Each finger and smaller toe has three phalanges; the thumb and big toe each have two. The phalange nearest the body of the hand or foot is call the "proximal" phalange; the one at the end of each digit is the "distal" phalange; and, of course, when there are three, the middle one is called the "middle" phalange.
Bones of The Foot -The instep is made up of five, elongated metatarsal bones that join the tarsus (the seven ankle bones). The distant heads of these bones form the ball of the foot. The tarsals and metatarsals are arranged and bound by ligaments to form the arches of the foot. A "tarsometataral ligament" joins the tarsus to the metatarsal bone. A longitudinal arch extends from the "posterior longitudinal ligament" at the heel to the "anterior longitudinal ligament" of the toe, and a transverse arch ("dorsal metatarsal ligament") stretches across the foot. These arches provide a stable, spring base for the body. At times, the tissues that bind the metatarsal become weakened and produce fallen arches or "flat feet." The "plantar ligaments" are in the sole of the foot. The "plantar calcaneonavicular ligament" joins the "navicular" bone in the ankle to the "calcaneus," or heel bone; the "plantar cuboideonavicular ligament" joins the navicular bone to the "cuboid" bone of the ankle. The "plantar metatarsal ligaments" bind the instep across the sole of the foot.
