目的：观察人胚胎三叉神经节细胞随胎龄增长的变化发育规律。方法取19～32 w人胚胎三叉神经节，光镜观察，进行细胞计数，图像分析仪测量三叉神经节细胞面积、周长、直径。结果随着胎龄增长三叉神经节细胞数目无明显变化，直径随胎龄增长而增大，面积和周长均随胎龄增大而明显增大。结论人胚胎三叉神经节细胞形态发育在7～8个月（32 w）时达成年人水平；但细胞数目随胎龄增长无明显变化。

Objective To observe the development of human embryonic trigeminal ganglion cells with fetal development.Method Embryonic trigeminal ganglion aged from 19 to 32 weeks were observed by light microscopy;the cells were counted,and image analysis instrument was used to measure the area,perime-ter and diameter of trigeminal ganglion cells.Results With the development of fetus,the number of tri-geminal ganglion cells showed no significant changes,but they grew in diameter while the area and perime-ter of cells increased significantly.Conclusion The morphology development of trigeminal ganglion cells in human embryo achieved adults′level at 7-8 months (32 weeks),but the number of cells showed no significant change with the development of fetus.
