Finger anatomy consists of bones, joints, tendons, and ligaments that work together to allow movement and dexterity. Each finger has three bones called phalanges, except for the thumb, which has two. The joints between these bones are known as interphalangeal joints, while the joint connecting the finger to the hand is called the metacarpophalangeal joint. Tendons connect muscles to bones, enabling finger movement, while ligaments provide stability by connecting bones to each other. The skin on the fingers is sensitive and contains many nerve endings, allowing for a sense of touch. Overall, the structure of the fingers is essential for various tasks, from gripping to typing.
