The endocrine system mainly controls the relatively slow metabolism of carbohydrates and water through the adrenal cortical tissue, the metabolism of nitrogen through the adrenal cortical tissue and thyroid gland, and the maturation and sexual behavior of germ cells through the pituitary and sex hormones. From an embryonic point of view, this gland develops from the pharyngeal epithelium near the fifth gill arch.
