Methods: Dil was embedded into the ophthalmic nerve, maxillary nerve and mandibular nerve in fixed postmortem human tissues of 6 fetuses. The tissue was incubated at 37℃ for 3 months, and then sectioned, mounted and observed under a fluorescence microscope after Dil had satisfactorily diffused. Results:The cells in the trigeminal ganglion of human fetus originating branches were arranged in the medio-lateral direction. Namely, the ophthalmic ganglion cells were distributed in the anterio-median part of the ganglion. The mandibular ganglion cells were distributed in the posterio-lateral part of the ganglion. The maxillary ganglion cells were distributed in the intermediant part between the cells originating the ophthalmic and mandibular branches. Conclusion:The cells in the trigeminal ganglion have been considered to be organized somatotopically in a medio-lateral direction reflecting the medio-lateral order of the three primary nerve branches (ophthalmic nerve, maxillary nerve and mandibular nerve). 【总页数】4页(P663-665,679) 【作 者】吴励;古丽尼沙·克力木;吐尔逊江·达地汗;甘子明 【作者单位】梅州市嘉应医学院附属医院放射科;新疆医科大学基础医学院人体解剖学教研室,乌鲁木齐830054;新疆医科大学基础医学院人体解剖学教研室,乌鲁木齐830054;新疆医科大学基础医学院人体解剖学教研室,乌鲁木齐830054 【正文语种】中 文 【中图分类】R74 【相关文献】 1.CT定位三叉神经节射频温控热凝术治疗原发性三叉神经痛2.三叉神经节定位注射法治疗三叉神经痛500例报告3.电刺激三叉神经节定位注射治疗三叉神经痛4.家兔面肌第一级感觉神经元胞体的分布及其在三叉神经节内的定位5.大鼠口面部躯体和上消化道内脏伤害性传入汇聚于三叉神经脊束间质核含CB神经元(英文) 因版权原因，仅展示原文概要，查看原文内容请购买 本文来源：https://www.dywdw.cn/2952e18e0a75f46527d3240c844769eae109a37b.html
