Most hormone secretions are regulated by negative feedbacks. The 3 main feed backs are:
1)(Blood level of certain chemicals controls hormone secretion) Blood composition; Ex: blood glucose levels control the insulin secretion.
2)(Hormones controlled by nervous system) Neural control; Ex: Epinephrine is release from adrenal medulla as result of nervous system stimulation.
3)(Hormone secretion controlled by other hormones) Hormonal control; Ex: hormones from pituitary gland act on the ovaries and testes causing release of sex hormones.
