[Histological study of the paracervical ganglion (Frankenhäuser) in mice (author's transl)].
The paracervical ganglion in dd-mice ranging in age from birth to 90 days was studied qualitatively and quantitatively by light microscopy. The paracervical ganglion is located just lateral to the fornix vaginae, and is shaped like a flattened cone. Out of the parenchymal cells, nerve cells are 97% and chromaffin cells are 3%, respectively. The chromaffin cells are arranged in small clusters or individually, and are scattered throughout the ganglion. Their chromaffin reaction varies in density from cell to cell. In neonatal mice, the ganglion consists of nerve cells and small spherical cells. With advancing age, as the small cells decrease in number, chromaffin cells appear. At 20 days of age, the ganglion is almost similar in structure to that of the adult. The nuclear and cellular size distribution curves of nerve cells are symmetrical in pattern after the age of 20 days. The nuclear size distribution curves of the chromaffin cells are symmetrical and are almost the same in pattern in newborns as in adults. The cellular size distribution curve of chromaffin cells are symmetrical before 20 days of age, but, with advancing age, the curve shifts to the larger size and becomes asymmetrical in pattern due to an increase of larger cells.
