Hypothalamus: master gland, controls the release and production of hormones in other glands, centre of the whole production, regulates how much hormones are produced and released. To start puberty, increase production of gnrh hormone and releases it in 2 hour pulses: 2 years before puberty starts leptin, driving force behind puberty. As body fat increases, amount of leptin increase: as leptin increases, crosses threshold- this causes increase of production of gnhr, triggers pituitary gland, fhs, lh- stimulates egg and sperm cells. Increases of estrogens and androgens responsible for physical changes during puberty: hair and breast growth. In turn, pituitary signals the gonads to create more hormones.
