Hgp axis without this, no puberty (stay small: hypothalamus, pituitary gland (master gland, gonads (testes & ovaries) Gonads release sex hormones into bloodstream: androgens & estrogens. Adults fully developed, teens immature and prone to high-risk behavior. Emotional center: passion, impulse, fear, aggression. Adults rely less on this, use prefrontal cortex more. Although no new hormones in adolescence, something signals the hgp axis to kick on. Leptin may be an important signal: protein produced by fat cells, must accumulate enough body fat, rising levels of leptin signal hypothalamus to stop inhibiting puberty (at least in females) Adrenarche: maturation of adrenal glands leads to physical (somatic) changes.
