ABSTRACT
In this investigation, macroscopic and microscopic structure of the adrenal glands was studied in 15 one humped camels. The results were compared with the available data on the humans and other species. The right adrenal was approximately bean shaped; whereas the left gland was almost triagular and in outline resembled the heart. The average weight, length, breadth, and thickness of the right and left glands were determined. Histologically, the adrenal glands were surrounded by a capsule of dense irregular connective tissue. Trabeculae were originated from the capsule and penetrated the cortex. The zona glomerulosa was formed of clusters cells. The zona fasciculata was consisted of radially arranged cords of cells and the cytoplasm of the cells of upper part was more foamy than the lower part. The cells of the zona reticularis were smaller and darker than the cells of the zona fasciculata. The endocrine cells of the adrenal medulla were arranged in irregular cords or clusters.
Key words: Adrenal glands, camel, cortex, histology, morphology
