Comparative Anatomy of Spleen: Histomorphometric Study in Human, Goat, Buffalo, Rabbit and Rat

Background: Comparative histology not only provides information regarding tissues of different mammals but also gives insight to understand human features in the background of informations on tissue of lower mammals. Methods : Splenic tissues from five mammals i.e., human, buffalo, goat, rabbit and rat were processed for histomorphometric study on capsule, trabeculae, lymphoid follicle and central arteriole. Result: Buffalo was one mammal having highest values for all the parameters while rat having lowest. Values in human splenic tissues are in between aforementioned maximum and minimum readings. Conclusion: Teaching materials are available in histology labs from lower mammals in medical colleges might give an insight for understanding human tissues if literature on comparative histology is made available.
