Phalanges are the bones that make up the fingers and toes in humans and many other animals. Each finger has three phalanges—proximal, middle, and distal—while the thumb has two. The toes also consist of three phalanges each, except for the big toe, which has two. These bones play a crucial role in the movement and dexterity of the hands and feet. The phalanges are part of the skeletal system and connect to the metacarpals in the hands and the metatarsals in the feet. They are essential for various functions, including grasping objects and maintaining balance while walking.
