Cytoarchitectonics of the ganglia functionally connected with the chorda tympani of the Syrian hamster.
A study on cytoarchitectonics of the parasympathetic ganglia which are functionally connected with the chorda tympani, was carried out in the Syrian hamster. Histological (paraffin and historesin) techniques were applied. The investigated ganglia are agglomerations of up to forty cells in ganglia of different sizes (from 50 to 400 microns in diameter), dispersed in three regions: 1. One large ganglion consist of 30 neurocytes in cross-sections and a few (3-4) smaller ganglia occurred within the hilus of the mandibular and major sublingual glands. 2. Along the main ducts of the salivary glands appear only 3 little ganglia, but at the level of crossing of these ducts with the lingual nerve-were found up to 12 large ganglia. 3. In the body and apex of the tongue the parasympathetic ganglia were dispersed mainly along ramifications of the lingual nerve. There were up to 20 agglomerations of cells different sizes and shapes. Because of this there is no justification in the hamster for distinguishing separate mandibular and sublingual ganglia.
