title: [The dorsal motor nucleus of the vagus nerve and its role in innervating the digestive tract].
abstract: Findings on topography of dorsal motor vagal nucleus neurons from which axons towards functionally different regions of digestive tract extend were analysed. Based on that and on the data available in literature main peculiarities of these cells topical organization were formulated. It is noted that "gastrointestinal" neurons are localised in dorsal motor nucleus as narrow stripes oriented caudo-rostrad. Stripes (or columns) of neurons from axons towards the digestive trace different parts arise do not cross. Digestive tract oral parts receive parasympathetic efferent inputs from neurons of medial and dorsomedial parts of the nucleus and caudal--from ventromedial cells of dorsal motor nucleus. Sites of maximal accumulation of initial "gastrointestinal" neurons that occupy an area within +0.5-(+)2.0 mm of functionally different regions of stomach and gut were demonstrated in cat and rat.
