Phalanges are the bones that make up the fingers and toes, crucial for dexterity and mobility in humans and many other vertebrates. They are arranged in proximal, middle, and distal segments, with the thumb and big toe lacking a middle phalanx, allowing for a range of movements essential for various functions like grasping and walking.
