Morphological examination of the proximal ganglion of the vagus nerve in the pig.

: This is the first report dealing with the localisation and morphology of the proximal (jugular) ganglion in the pig. Six 3-months-old pigs of both sexes were used in this study. Tissues were stained with three histological methods: Kluver-Barer counterstained with Cresyl violet, Haematoxylin-eosin and Mayer's haematoxylin. The localisation and morphological features of the ganglion and ganglionic neurones were described and discussed.
