Disorders of Thyroid Function

  • Paolo Cavarzere
  • Luciano Tatò


The thyroid is a bilobed gland located in the neck region, made up of two types of cells: the follicular cells which produce thyroxine and the parafollicular cells which produce calcitonin. The follicular cells are the predominant cell population in the gland and they derive from the endoderm, whereas parafollicular cells are of neuroectodermal origin [1]. These different types of cells migrate from their respective sites of origin to ultimately merge in the definitive thyroid gland. The follicular cells organize into thyroid follicles whereas the other type of cells scatters into the interfollicular space [2]. Most thyroid function disorders are related to developmental or enzymatic defects involved in the process of thyroid hormone production.
