Normal structure and funaction of the thyroid • The thyroid gland (normal weight 20—30 g) is composed of follocles which are lined by cuboidal epithelial cells and contain a proteinaceous stored secretion (‘colloid’). The main function of the thyroid epithelial cells is the synthesis of the iodinated amino acids, thyroxine (T4) and tri-iodothyronine(T3)
Normal structure andfunaction of the thyroid. The secretion of T3 and T4 is undernegative feedback control by TSH from theanterior pituitary The thyroid also contains a population ofcells known as C-cells; these are sparselyscattered throughout the gland and secretecalcium metabolism
