Tracheo Bronchial Tree and Its Morphological Pattern of Corrosion Cast Model

The goat lung tracheo- bronchial tree pattern was studied to overcome the wet dripping formalin specimens on the dissection table. The ruminant lung has an additional tracheal apical bronchus before the level of the tracheal bifurcation. The silicon resin which is normally used in water proof/sealing material in many fields. The silicon was injected by injecting gun through trachea and further gently wiped out towards the rest of the lung area. It was filled with gentle manual pressure by kneading like wheat flour. The resulted corrosion cast specimens were pleasant appearance, easy to handle and demonstrate as teaching tools. It can be further displayed as anatomical museum models to educate at large.
