[Distribution of the vagus nerve of the stomach and certain lymph nodes of the sheep in the prenatal period (author's transl)].
The goal of this study was the investigation into the vagus nerve structure in the ruminant stomach, and a description of the participation of this nerve in the stimulation of the atrial lymph nodes of the rumen and dorsal abomasal lymph nodes. This survey was carried out on 30 sheep fetuses, whose ages are designated according to Zietzschmann and Krölling (1955). The fetuses came from the third to fifth months of pregnancy. Observations and general morphological nature may be summarized as follows: 1. to the wall of the rumen reach atrial branches coming from both vagus trunks plus a dorsal ruminal branch, and a right ruminal branch coming from the dorsal vagus trunk, 2. the reticulum receives reticular branches, coming from both vagal trunks, 3. the omasum is innervated by omasal branches of the dorsal vagus trunk plus an omasoabomasal branch coming from the ventral vagus trunk, 4. to the wall of the abomasum reach the reticulo-abomasal and pyloric branches coming from the ventral vagus trunk plus a branch to the major abomasal curvature and a visceral abomasal branch coming from the dorsal vagus trunk, 5. arterial lymph nodes of the rumen receive innervation from the reticulo-abomasal branch or the pyloric branch, both leaving from the ventral vagus trunk, 6. dorsal abdominal lymph nodes innervated by nerve branches coming from a parietal abomasal branch, coming also from the ventral vagus trunk.
