Most girls have this data.
Most people have a left hand and a right hand, except for deformity or hyperplasia at birth. Each hand has five fingers, including the index finger, middle finger, ring finger, little finger (also called tail finger) and only two thumbs, but it is also possible to have a sixth finger at birth. There are nails at the tips of the five fingers, each with its own length, which is longer than the palm end. The center of the palm is called palm print, and there are palm prints in the palm. Palmprint will deepen with time, so the palm print of the elderly will always be deeper than that of the newborn. There are fingerprints on the palm and fingers, but not on the back of the hand.
