Period of rapid physical maturation involving hormonal and bodily changes that take place in early adolescence: signs of sexual maturation, menarche. A girl"s first menstrual period: growth spurt. Girls" onset of puberty between 9 to 15 years of age. Boys" onset of puberty between 10 to 17 years of age. Powerful chemical substances secreted by endocrine glands and carried through bloodstream: hypothalamus. Brain structure involved in eating and sexual behavior: testosterone. Hormone associated in boys with genital development, increased height, deepening voice: estriadol. Hormone associated in girls with breast, uterine, and skeletal development.
