Goitre is caused due to deficiency of iodine in diet because iodine is needed for the synthesis of thyroid hormone. Hypothyroidism leads to goitre. Adrenal cortex of adrenal gland secretes glucocorticoids which regulates carbohydrate metabolism. The secretion of parathyroid hormone (PTH) is regulated by the circulating levels of calcium ions.
