Abstract:
The histomorphological aspects of cerebellar cortex were studied in 18 Large White Yorkshire pigs at different age groups. The cerebellar cortex revealed three layers viz., the molecular layer, the Purkinje cell layer and the granular layer. Five neuronal cell types were observed in the cerebellar cortex viz., the granule cells, Purkinje cells, stellate cells, Basket cells and Golgi cells. There was an increase in the dendritic arborization from preweaner to grower age group, whereas there was discontinuation in dendritic branching in finisher age group. Significant difference was noticed in width of the layers between preweaner and grower age groups, whereas no significant difference was observed between grower and finisher age group. Lipofuscin pigmentation was seen only in Purkinje cells of the cerebellar cortex and it was increased from grower to finisher age groups. There was a slight decrease in the neuronal cell number, size of cell bodies, amount of Nissl substance and an increase in neuropil, glial cell number was noticed with advancement of age.
