Ring finger
Ring Finger
The Ring Finger (/ˈrɪŋ ˈfɪŋɡər/) is the fourth digit of the human hand, located between the middle finger and the little finger. It is also known as the fourth finger.
Etymology
The term "ring finger" comes from the tradition of wearing a wedding ring on this finger, a custom that can be traced back to ancient Rome. The Romans believed that the vena amoris or "vein of love" ran directly from the heart to the ring finger.
Anatomy
The ring finger is composed of three phalanges: the proximal, middle, and distal phalanges. It is controlled by the ulnar nerve and the flexor digitorum superficialis and profundus muscles. The ring finger shares a flexor muscle with the little finger, which can limit its independent movement.
