摘　　要：目的以端脑横切面为基础,研究并充实端脑形态结构两侧不对称性问题的解剖学知识;通过对端脑髓突的不对称性研究,论证通过髓突定位脑回方法的可行性和适用性。方法选取30例成年人尸体正常头颅标本,以过蝶平面及其沿线为基准,锯切头颅至脑表面留下锯痕;开颅取脑,并对不同脑回染上不同颜色以方便区分;以锯痕为基准,用自制切片机平行锯痕切制6 mm厚的脑切片。通过观察周边脑回的不同染色区分辨认脑回,再观察对应髓突的分支数目、分叉及方向等。对所得资料进行分析并作统计学处理。结果在横切面上,大多数脑回对应的髓突在数目和倾斜角度上是对称的。结论通过髓突定位脑回机能区的方法在端脑的横切面上同样具有较好的可行性和适用性。Objective To study the asymmetry of medulla on the sectional plane to support the way of localizing gyris by the neurapoph- ysis, and to enrich the anatomical knowledge about the telencephalie sectional plane. Methods Slected 30 adult normal head specimens. Head specimens saw cutting were made through the planum sphenoidale till the surface of the brain were marked. Colored the different gyris with different colors so as to distinguish. Then cut the brain parallel to the marked line to make brain slices of 6 mm. Observed the correspond- ing neural process by different staining of brain slices. The number and direction of neurapophysis branches of the corresponding neurapophys- is were observed. And these data were statistically analyzed and processed. Results On the telencephalic sectional planes, most of the corre- sponding neurapophysis of gyrus were symmertrical in the number and direction of neurapophysis branches. Conclusion It is reliable and practical to localize gyris with neurapophysis on telencephalic sectional planes.
