Tulang Jari refers to the bones in the fingers of the human hand. Each finger contains three bones called phalanges, except for the thumb, which has two. These bones are essential for hand movement and dexterity, allowing us to grasp and manipulate objects effectively. The phalanges are categorized into three types: proximal, middle, and distal. The proximal phalanx is closest to the hand, the middle phalanx is in the center, and the distal phalanx is at the tip of the finger. Together, these bones provide structure and support, enabling a wide range of hand functions.
