Anatomical studies on the cerebellum of the donkey of Egypt.
The cerebellar mass forms about 34.4 cm3. The ratio to the brain mass is 1:9.8. The cerebellar dimensions are 5.2 cm in width, 3.9 cm in height, and 4.9 cm in the rostrocaudal length. Its weight is 37.6 g, it forms a relation of 1:9.4 (10.8%) to the weight of the whole brain mass. The cerebellar lobulation of the donkey is as follows: The rostral lobe consists of median lobules (Lingula, Lobulus centralis, and Culmen) and lateral lobules (Vinculum lingulae, Ala lobuli centralis, and Lobulus quadrangularis). The caudal lobe consists of median lobules (Declive, Folium, Tuber, Pyramis, and Uvula) and lateral lobules (Lobulus simplex, Lobulus ansiformis, Lobulus paramedianus, Parafloccularis dorsalis, and Parafloccularis ventralis). The flocculonodular lobule is made up a median lobule, the Nodulus, and the lateral lobule is the Flocculus. All measurements, numbers of the superficial folia for each lobule as well as the folia which border the fissures were recorded. From the investigation, some morphological differences between donkey and horse can be concluded.
