Abstract: 

In this study 20 turkeys were slaughtered then heads detached from body. Roof of cranium removed and full brain that cerebellum attached to that moved to 10% inactive formalin. Some samples were choice for anatomical studies. Cerebellum's appearance, dimension, color and shape were evaluated. Some samples used for histological studies and tissue sections stained with four following methods; H & E, Mallory, Periodic Acid Schiff staining method, Bielschowsky. Sections studied with light microscope. As result of anatomical study it became distinct that cerebellum located behind of longitudinal sulcus of cerebrum hemispheres. Cerebellum in turkey is similar to fly larva and nodular in front and extended in behind. Color of cerebellum is bright cream that contains 14 small transversal fissures (pleats). Cerebellum peduncles stretches to Brain Bridge and a pair of brain peduncle get out from cerebellum. A small tubercle is located in ventral part of cerebellum that is continues of upper pleats. White matter in cerebellum is located in middle part with tree shape, gray matter is located outer part and surrounded the white matter. Almost in all samples 6 main branches is present. Cerebellum doesn't have lobe and just have a vermis. Histological study has shown that cerebellum surface has very deep pleats. In gray matter there are three layers; molecular, purkinje and granular. Purkinje cell cytoplasm has been shown severe positive P.A.S reaction furthermore this condition was seen in cerebellum vessels (strong pink). Axons fibers in white matter get dark filiform shapes and in granular layer dark filiform fiber has been shown in some parts. In Mallory staining collagen fibers in cerebellum vessels and pia matter obtained blue color, white matter in this staining get numerous amount of orange colored.
