Document Summary

Derived from the latin word pubscere" which means to grow hairy . The body undergoes a biological revolution that dramatically changes the adolescent"s anatomy, physiology, and physical appearance. Gradually increases productions of gonadotrophin-releasing hormone (gnrh) Recent evidence indicates that this occurs once a threshold level of body fat is reached. Fat cells produce leptin that provides the signal to the hypothalamus: has to have a certain about before its signaled. Sex differences in hormonal changes during puberty. Extremities are the first to hit the growth spurt. Not all parts of the body grow at the same pace: we feel clumsy. Asynchronicity: explains the gangly look in early adolescence. Prior to puberty girls & boys have similar muscle mass: men tend to build more muscle. During puberty, body fat increases more for girls than boys: women tend to store body fat which is associated with biological needs. Development of sex organs: secondary charactistics.
