[Light and electron microscope study of the cerebellar cortex in the cow, sheep and goat]

In order to investigate the fine structure of the cerebellar cortex of domestic ruminants, tissue specimen were taken of the Lingula, Declive, Nodulus, Lobus paramedianus and Flocculus of 30 cows, sheep, and goats. The following techniques were used: Luxol-Fast-Blue and Nisslstaining, Bodian and Golgi impregnation according to BUBENAITE and to KEMALI (1976). Electronenmicroscopically, differences between these species were seen only in the thickness of the three layers and in the size and topography of the 7 different cells and the fibres of the cerebellar cortex. In contrast to other species, soma and fibres of the Purkinjecells often contained numerous lamellar bodies. As in other animals the granular endoplasmic reticulum is arranged in form of nuclear caps.
