Abstract Freilegung der Schädelkapsel von Muskel- und Bindegewebe, Eröffnen der Labyrinthhohlräume durch Flachschnitte mit dem Skalpell, vorsichtiges Herauspräparieren der drei häutigen Bogengänge. Benutzung der Präparierwerkzeuge.
As a first step, the chondrocranium of the dogfish is cleaned from the skin and adhering muscles from above. By cautiously working with a scalpel, thin superficial layers of the cartilage are cut away until the holes of the three semicircular ducts are opened. The rest of the preparational proceeding is done by means of a pointed steel forceps which is used for cutting or breaking the cartilage away. In the final spots, the results of the preparation is displayed: The three semicircular ducts together with three ampullae and the utriculus in their natural spatial arrangement.
