Document Summary
Adolescence is a transitional period between child-hood and adulthood. Usually beings at around age 13 and ends at age 22. Adolescent growth spurt is brought on by hormonal changes, and it typically starts at about 11 years of age in girls and about two years later in boys. Pubescence is used to describe the two-year span preceding puberty during which the changes leading to physical and sexual maturity take place. Secondary sex characteristics are physical features that distinguish one sex from the other but that are not essential for reproduction. Puberty is the stage during which sexual functions reach maturity, which marks the beginning of adolescence. Primary sex characteristics are the structures necessary for reproduction. Menarche is the first occurrence of menstruation. Girls who mature early and boys who mature late seem to have more emotional difficulties with the transition to adolescence. Early maturation often thrusts both sexes toward the adult world too soon.
