    The Tanner Scale describes, both pictorially and descriptively, the external changes that occur in the time period between the onset of puberty and the achievement of full maturity for both girls and boys. Characterizations of pubertal status are assessed by breast development in girls, genital development in boys and pubic hair growth in both. The Tanner...
