The Tanner scale (also known as the Tanner stages or sexual maturity rating (SMR)) is a scale of physical development as pre-pubescent children transition into adolescence, and then adulthood. The scale defines physical measurements of development based on external primary and secondary sex characteristics , such as the size of the breasts ...
The size of the testicles is among the parameters of the Tanner scale for male genitals, from stage I which represents a volume of less than 1.5 ml, to stage V which represents a testicular volume of greater than or equal to 20 ml. Testicular size reaches maximal adult size about 6 years after the onset of puberty.
Cortical white matter increases from childhood (~9 years) to adolescence (~14 years), most notably in the frontal and parietal cortices. [8] Cortical grey matter development peaks at ~12 years of age in the frontal and parietal cortices, and 14–16 years in the temporal lobes (with the superior temporal cortex being last to mature), peaking at about roughly the same age in both sexes ...
Biologically, an adult is a human or other organism that has reached sexual maturity. In human context, the term adult has additional meanings associated with social and legal concepts. In contrast to a legal minor, a legal adult is a person who has attained the age of majority and is therefore regarded as independent, self-sufficient, and ...
Adult height can be predicted from measurements of height at three years of age; males are approximately 53% of their adult height and females, 57%. Legs grow faster than arms. Circumference of head and chest is equal; head size is in better proportion to the body. "Baby fat" disappears as neck appears.
Adult development encompasses the changes that occur in biological and psychological domains of human life from the end of adolescence until the end of one's life. Changes occur at the cellular level and are partially explained by biological theories of adult development and aging. [ 1 ]

An alternative approach to the atlas method just described is the so-called "single-bone method" where maturity scales are assigned to individual bones. [7] [8] Here, a selection of bones are given a score based on their perceived development, a sum is totaled based on the individual bone scores, and the sum is correlated to a final bone age.
