Hypothalamus Releasing hormone : stimulate pituitary Inhibitory hormone : stop pituitary Parathyroid Parathormone : filter calcium from nephrine filtrate Thymus Thymosin: development of immune system Thyroid Thyroxine , triiodothyronine: maintain BMR and breakdown of carbs,protein,fat Calcitonin: maintain calcium level in blood Pineal Melatonin: helps in sleep,mood and rhythm of biological clock Adrenal Adrenal cortex Mineralocorticoids: absorption of sodium and removal of potassium glucocorticoids : breakdown of carbs,protein,fat Immunosuppressive anti inflammatory Sex corticoids: enhancement of secondary sexual characters Adrenal medulla Adrenaline and noradrenaline: emergency stress Gonad Testes Testosterone , sperm Ovaries Oestrogen , progesterone( maintenance of uterus wall) Pituitary Growth hormone(GH) :height and bone elongation adrenocorticotrophin(ACTH) : stimulate adrenal cortex to produce cortisol prolactin(lactogenic): produce milk post childbirth Thyroid stimulating hormone (TSH) : secretion of thyroid gland Follicle stimulating hormone (FSH) : secondary sexual characters Luteinising hormone: secretion of progesterone and testosterone Oxytocin: contraction of uterus during childbirth Vasopressin: reabsorption of water Melanocyte stimulating hormone : stimulate melanocyte to produce melanin Pancreas Alpha - glucagon(maintain blood sugar level from not going too high) Beta- insulin(maintain blood sugar level from not going too low)
