Objectives: Comparative histological studies of pineal gland of man and fowl has been made to observe structural differences if any between these two species. Background: Some works have been done sporadically on laboratory animals and on birds and also in human correlating with other parameters. In this investigation an approach has been made to observe the cellular organization of the pineal gland parenchyma in these two vertebrates, having different physiological aspects. Methods: Some special stains were used to observe connective tissue elements (Reticulin,collagen and elastic fibers) along with conventional H and E stains. Result and conclusion: The lobular character of the gland, connective tissue septa, shape and size of the pinealocytes were found to be almost common in both species. Major differences seen in fowl pineal gland are the presence of ependymal cells on the walls of the lumen of the lobules and absence of corpora arenacea. |
