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.
采用光学显微镜对出生至90日龄的dd小鼠的子宫颈旁神经节进行了定性和定量研究。子宫颈旁神经节位于阴道穹窿外侧，呈扁平锥形。在实质细胞中，神经细胞占97%，嗜铬细胞占3%。嗜铬细胞成小簇排列或单个存在，散在于整个神经节内。它们的嗜铬反应密度在细胞之间各不相同。在新生小鼠中，神经节由神经细胞和小球形细胞组成。随着年龄的增长，小细胞数量减少，嗜铬细胞出现。在20日龄时，神经节的结构与成年小鼠几乎相似。20日龄后神经细胞核和细胞大小分布曲线呈对称模式。嗜铬细胞核大小分布曲线呈对称，在新生儿和成年人中模式几乎相同。嗜铬细胞的细胞大小分布曲线在20日龄前呈对称，但随着年龄增长，曲线向较大尺寸偏移，由于较大细胞数量增加而变得不对称。
