Studies on the development of cerebellum of one-humped camel (Camelus dromedarius)

Abstract

A histomorphological study of the development of foetal cerebellum was conducted. It was observed that at first trimester there were fewer fissures in the folia which progressively increased towards the third trimester. It was also observed that the histology of cerebellum of camel foetus at first trimester showed clear distinct external granular layer which was thin densely parked with cells which progressively decrease in thickness and amount of cells towards the third trimester. The next layer which was the molecular layer with less cell (stellate and basket) compared to the external germinal layer increased in volume with increased age. The molecular layer was followed by a densely cell (Golgi and granule) packed internal granular layer which progressively increased from first trimester to the third trimester. Purkinje cells which were in-between molecular and internal granular layer were not seen in the first trimester but were gradually becoming more visible in the subsequent trimesters. The development of the cerebellum in this study is similar to what was observed in most of the animal species.
