Document Summary
These domains are dynamic and they interact with one another. Puberty is a neuro-endocrine process that provides stimulation for rapid physical changes that accompany development from childhood to adulthood. Puberty is gradual process that begins at conception: there are no new hormones that are being produced, no new bodily systems develop. Tanner scale covers primary (penis, vagina) and secondary (breast development, pubic hair) sex characteristics. Produces, circulates, and regulates hormone levels in body. Hormones: specialized substances secreted into blood stream and travel throughout body, gonadotropin-releasing hormone (gnrh) neurons. Glands: organs that stimulate particular parts of body to respond in specific ways. Organizing role: prenatal hormones program brain to be masculine or feminine, patterns of behavior as result of this organization may not appear until adolescence. Increase in certain hormones at puberty activates physical changes. More estrogen and androgen linked to more risk-taking behavior. The endocrine system: hpg feedback loop (hpg axis)
