Abstract :
Brain size varied between different animals and even individuals according to body size. These variation, influence the size, form and position of ventricular system. Education of some structures of organs such as ventricular system in anatomy may be hard. With regard to the cases, in this research, we evaluated the way of providing of brain ventricular cast in Lori sheep. For this purpose, thirteen number of healthy sheep heads were used. After separation of skull roof bones, the heads fixed in fixative solution. Metal needles positioned in suitable point and leading it into the lateral ventricles. Molding materials include Silicone RTV and adhesive stone injected. After preparation of casts, the structure, form and position of brain ventricles clear and studied.
