Abstract

A histomorphological comparative study of the thyroid glands of 55 healthy adult (8-15 years) camels (Camelus dromedarius) of different sex group A (28 Males) and group B (27 Females), were investigated under gross and microscopic anatomical differentiation. Gross studies revealed that thyroid glands of both sex were located in between the third ring of trachea and the laryngopharynx portion of the pharynx and had two lobes, connected by an isthmus. They female gland appeared to be deeply reddish brown than the male in colour. The values of weight, length, width and diameter of both sex glands were shown to have significant difference with the male been greater than the female (P>0.05). Histological observation revealed that the male thyroid gland consisted of more connective tissue capsule than the female and traberculae were found extending from the capsule deep into the parenchyma of the gland in the female than in the male, which divided it into lobules. These shown that lobation is more pronounced in female than in male with each lobule consisted of two sized follicles in variable numbers, the large and small. The large follicles predominate in the male and were lined by low cuboidal epithelium, while the small follicles predominate in the female were lined by high cuboidal to columnar epithelium. The follicles had colloid material in their lumen, probably an apocrine secretion from the lining epithelial cells of both sex.
