[Relations between the accessory nerve and the distal ganglion of the vagus nerve in sheep during the prenatal period].

This contribution presents the results of morphological studies regarding the nervus accessorius and the ganglion distale nervi vagi of the sheep during the prenatal period. Special attention was paid to the roots of the brain and spinal medulla, which are implicated in the formation of the nervus accessorius, and the region of the spinal medulla in embryos at different stages of development. We investigated the relationship between the above nerve and the ganglion distale nervi vagi. The morphology of this ganglion was also investigated, and its external structure is described.
