    hi, i was listening to kaplan anatomy lectures and it was mentioned that the C cells of thyroid gland are derived from 4th pouch together with the superior parathyroids. however in the kaplan anatomy text, it mentions that c cells are derived from neural crest. knowing that pouches are from endoderm, which one is the right answer? thanks:rolleyes:

    pretty sure C cells come from the neural crest. This is why you get the multiple endocrine neoplasias (MEN II and III). Someone correct me if I am wrong

    c cells--> medullary thyroid cancers and the chromafin cells (which are also from neural crest) give a pheo
