The term "digitus minimus" refers to the smallest finger on the human hand, commonly known as the little finger or pinky. It is located on the outer edge of the hand and plays a role in grip strength and hand dexterity. The digitus minimus consists of three bones called phalanges and is controlled by several muscles and tendons. In addition to its anatomical significance, the digitus minimus is often associated with various cultural practices. For example, in some cultures, a pinky swear is a gesture of promise or commitment. The little finger also has a role in certain musical instruments, such as the piano and guitar, where it is used to reach notes that are farther away.
