Abstract

In the background that there is scanty literature on the ultrastructure of ultimobranchial bodies of the fresh-water turtles, this paper describes the ultrastructure of the gland of freshwater turtle Lissemys punctata granulosa. The gland was dissected out and subjected to transmission electron microscopic analysis to examine the structure of the gland. The gland is composed of a single type of cells with a few secretory granules of similar size, large cytoplasmic bodies, Golgi region, and fewer mitochondria.

Abstract

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.

Abstract

The fresh-water turtle Lessemys punctata granusa, possess two pairs of parathyroid glands. The anterior or rostral parathyroid are generally embedded in the thymus tissue. The posterior parathyroids lie between the aortic arches. Each parathyroid gland is surrounded by a connective tissue capsule and is composed of elongated cell cords and follicles. This turtle possesses a single pair of ultimobranchial glands located bilaterally, which are closely associated with the posterior pair of parathyroid glands. The ultimobranchial glands possess cells arranged in the form of follicles around a central lumen of varied sizes.

Abstract

The snake Oligodon arnensis possesses two pairs of parathyroid glands. The rostral parathyroids (rPTG) are located at the bifurcation of the carotid artery, behind the angle of the jaw. The caudal parathyroids (cPTG) are located in the thyro-thymic region. The parathyroid gland is surrounded by a connective tissue capsule, and composed of cell cords of a single type of cell. Oxyphil cells are absent. The gland is profusely supplied with blood vessels.
