Regardless of your gender, your body changes from the moment you are born and continues to do so as you age. Infancy (years 0-2), childhood (ages 3–11), adolescence (ages 12–18), and young adulthood (ages 18–24) are some of the stages that make up human development. As you can guess or have already discovered, a lot can happen between childhood and young adulthood. As we mature, being aware of these changes and how they occur will help us become more self-conscious and aware of our surroundings. According to Puberty Education, hormones associated with puberty are responsible for changes in brain structure and function. Our bodies and minds go through significant changes during puberty that get us ready for adulthood. Our bodies and minds must adjust to constant changes as adults. The hormones that mold our bodies and thoughts throughout puberty also play a significant influence later in life. Long before birth, testosterone, and estrogen start to play a part in the formation of new neurons and their guidance as they develop into the brain's structure. These hormones permanently change the way the brain is organized and structured during puberty.
