Ultrastructural Organization of Parathyroid Gland of Freshwater Turtle Lissemys punctata Granulosa

Parathyroid gland of the fresh-water turtle Lissemys punctata granulosa was examined during March to May. The gland is composed of chief cells and rare oxyphil cells. The chief cells are arranged as solid cords and differentiated into dark and light cells. The cytoplasm of oxyphil cells is packed with mitochondria, which obscure the other organelles. The chief cells possess numerous ribosomes, mitochondria, Golgi complex and microfilaments.
