- Principal (chief) cells, the more numerous of the

parenchymal cells of the parathyroid, are responsible for

regulating the synthesis, storage, and secretion of large

amounts of PTH. Principal cells can replicate when they are

chronically stimulated by changes in blood calcium levels.

- Oxyphil cells constitute a minor portion of the

parenchymal cells and are not known to have a secretory

role.
