The examination was carried out on vagal trunks of six domestic pigs in the age of 5–6 months. After fixing, the preparations were stained with cresyl violet according to Klüver-Barrera’s method and with the methylene blue according to modified Nissl’s method. It was stated that most ganglionic cells were present in the thoracic part, and the fewest in the abdominal part. The cells structure is the same in all parts studied. Majority of the cells is of 20 to30 μm size. Comparing the left and the right vagus nerve, no greater differences were spotted as far as the positioning of the ganglia, their number and size was concerned; the cell shape and their size and number do not point to the differentiated structure in the opposite nerves.
