| Abstract | ||
| Morphological and histological aspects on the cerebellum of (Buzzard) was Studied to describe the size, design and structural variation that related to birds behavior and function. The results of morphological aspects revealed that the expanded tuber cerebellum was protruded forward to cover the diencephalons and backward to cover the medulla oblongata. The vermis was involved three strongly folded lobes. Ten long and expanded primary folia were found in longitudinal sagittal sections, the folia (IV, V, VI, VII) were expanded and subfoliated. Histological aspects of this organ were studied with the help of rotary microtome and slides stained with heamatoxylin and Eosin (H & E) and periodic acid schift reagent (PAS) methods. The results of microscopicexamination indicated that there are three distinct layers in the cortex (gray matter). 1- Thick outer punctuate molecular layer. 2- Single middle large shaped Purkinje cell layer. 3- Thick inner granular layer. The white matter which formed the medulla has a tree like appearance of deep nuclei groups embedded within the white matter in the center of the cerebellum. | ||
