This is a myth that brain is lost during puberty. Nothing of the sorts happen.
The challenging part is being confident and comfortable with the changes going on. Do not worry, all the changes are for the good.
Your Brain, like it does with nearly every other body process. The Pituitary gland in the base of the brain !
The brain controls you.
Puberty is natural and takes around 5 years to pass. Everything happens to change slowly. Adapting to these changes will just be a part of day to day living, you will not notice having to adapt. It is all a part of growing up from child to adult.
Puberty is a noun.
I'm pretty positive they have to. If they didn't they will have no pubic hair, no sperm, a small penis, and probably will stay immature as a kid because part of puberty is hormones and emotional changes.
Physical changes in girls can include the development of breasts, the growth of pubic hair and underarm hair, menstruation, and changes in body shape as they go through puberty. These changes are a part of the natural process of maturation and development during adolescence.
I'm not really sure what you're asking. Menarche, or a girl's first period/first menstrual cycle, can only occur during puberty, is a part of puberty, and by definition is generally considered to be one of or the LAST change the occurs in puberty for girls. Other changes such as growth spurts, changes in breast tissue that progresses to the development of breasts, hair growth in new places (e.g. underarms, pubic hair), and all the changes that are occurring in less obvious ways (changes in the brain, hormone levels, etc) all usually happen prior to or at least start before menarche (in normal, healthy girls). If you are really asking perhaps "why it is considered the culmination of puberty in girls", then the above is your answer (it happens last, or close to last). But if you did indeed mean the question exactly as written, I suppose the real answer is "It's not an indication of puberty for girls." It would simply be a definition, I suppose - menarche merely means a girl, who is currently going through puberty, has experienced another change that happens during that time. So many other changes will happen first, like I explained above, so menarche is not used as an "indication" as far as I know. It's kind of like asking "why is gaining 10 pounds an indication of increasing weight?" Menarche is simply a part of puberty, just like gaining 10 pounds is a part of increasing weight.
every part of your body has hair, but it is not part if puberty. It is normal.....
"The New Deal" was a program initiated by Franklin Roosevelt in 1932. In the end, this program was part of the changes that allowed the United States to eventually join the effort to liberate Europe in the Second World War.
There are no puberty "rights". Everyone goes through puberty and it is a natural part of life and growing up.
