The scanning electron microscopy of the thyroid gland was done in 16 naturally dead camels (n=16) of both sexes at Veterinary Clinical Complex, RAJUVAS, Bikaner, Rajasthan. The scanning electron microscopy (SEM) of collected thyroid gland was done at Department of Veterinary Microbiology, College of Veterinary and Animal Science, Bikaner. The thyroid gland was covered by a thick fibrous connective tissue capsule and the parenchyma was made up of numerous follicles. The external forms of the follicles were mostly oval and elliptical. Some irregular follicles were observed. The size of the thyroid follicle ranged between 550-800 |rm in summer and 80-350 pm in the winter season. The interfollicular or interstitial connective tissue separated the follicles. The parafollicular or “C” cells were also seen in between the thyroid follicles. The thyroid follicles were filled with gel-like round substances called colloid substances. The follicular epithelium cells of the thyroid gland were squamous to low cuboidal in shape.
