Abstract
In order to study the differentiation and distribution of the chromaffin cells in the adrenal medulla of camel. Thirty specimens of adrenal glands of male and female were fixed using two concentrations of Regauds solution. Fifteen specimen were fixed in Regauds solution containing 3% of potassium dichromate for 24 hours, and the another 15 specimens were fixed by same solution containing 8% of potassium dichromate for two weeks. Routinely processed by using histological technique and studied by light microscope, the results demonstrated that the adrenal medulla included columnar cells its mean length was (22)µm and its cytoplasm stained brownish color and these are secreting adrenaline ,and arranged in outer zone ,and an inner zone of small polyhedral cells, its mean length (9.5) µm and its cytoplasm stained yellowish and secreting nor-adrenaline. The central vein of the adrenal medulla contained smooth muscle fibers in its wall , which was not mentioned by other investigators in camel.
