The pinky finger, also known as the little finger, is the smallest digit on the human hand. It is located on the outermost side of the hand and typically has three bones called phalanges. The pinky plays a role in grip strength and hand coordination, contributing to various hand functions. In many cultures, the pinky finger is associated with gestures and symbols, such as the pinky swear, a promise made by intertwining pinky fingers. Additionally, the pinky is often involved in activities like playing musical instruments, where its dexterity can enhance performance.
