The plate is only found in children and adolescents; in adults, who have stopped growing, the plate is replaced by an epiphyseal line. This replacement is known as epiphyseal closure or growth plate fusion. Complete fusion can occur as early as 12 for girls (with the most common being 14–15 years for girls) and as early as 14 for boys (with ...
The pronate grasp involves using the middle finger and thumb. Children at this stage are able to use their thumb for tactile prehension. This stage can be mastered by the age of 2–4 years old.

Midphalangeal hair, or the presence/absence of hair on the middle phalanx of the ring finger, is one of the most widely studied markers in classical genetics of human populations. Although this polymorphism was observed at other fingers as well, for this kind of research, the fourth finger of the hand has been conventionally selected.
Doctors share why fingers get pruney in water, including causes of wrinkled fingers and toes, treatments, and the theory behind the evolutionary response.
