Document Summary
Age of majority: the age to be legally considered an adult. Skeletal age estimation involves correlating biological age (or physiological age) with chronological age (the length of time a person has been alive) Traits or processes useful as age indicators should change unidirectionally with age, correlate with chronological age and change consistently across individuals. Chronological and biological age are not perfectly correlated because biological age varies as a function of genetics, nutrition, environmental factors and activity level, among other factors, while chronological age is measured by time. Trajectory effect: the discrepancy between biological age and chronological age widens as people get older. In childhood, the skeleton changes as a function of growth and development; these changes are influenced by genetics and intrinsic factors. In adulthood, the skeleton begins to show degenerative changes as the body attempts to maintain homeostasis; these changes are influences largely by extrinsic factors.
