A study on the histomorphology and histochemistry of the thyroid and parathyroid glands in sheep was conducted in the prenatal and post natal age groups of sheep. The capsule of the thyroid gland consisted of two layers of connective tissue separated by a layer of adipose tissue. The stroma showed the presence of solitary ganglion cells. The parenchyma of the thyroid gland consisted of solid epithelial cords separated by mesenchymal tissue. In sheep embroys at 25 days of gestation, precursors of C cells called dark cells were found in the ultimobranchial bodies. Multiple ciliated follicular cells were observed in the developing thyroid of dogs and were prominent at three weeks prior to the expected date of birth. The thyroid follicles were irregular in outline and the diameter increased in the older subjects. In buffaloes, the larger follicles were present in the deeper zone of the thyroid gland. The follicles were lined by follicular cells and light cells. | Histomorphology and histochemistry of the thyroid and parathyroid glands in sheep - An overview
