 | | Normally, various hormones are produced and secreted by the endocrine glands (see endocrine system), including the pituitary, thyroid, parathyroids, adrenals, ovaries, testes, pancreatic islets, certain portions of the gastrointestinal tract, and the placenta, among the mammalian species. |
 | | The hormones of the anterior pituitary include thyrotropin, adrenocorticotropic hormone, the gonadotropic hormones, and growth hormone; the posterior pituitary secretes antidiuretic hormone, prolactin, and oxytocin. |
 | | Plants, too, have a hormonal system, which includes the auxins, the gibberellins, the cytokinins, and substances associated with the formation of flowers, tubers, bulbs, and buds. |
