目的 探索髓突与额叶脑回在冠状面上的对应规律,为影像学上通过髓突定位额叶脑回奠定解剖形态学基础.方法 选20例正常人脑标本,用广告颜料对额叶脑回染色,作层厚6 mm之冠状切脑片,选取其中典型层面,观察分析额叶脑回与髓突之间的对应性并总结规律.结果 额上回、额中回和额下回所对应的髓突绝大多数为1支,极少数为2支.髓突方向在不同的冠状切面固定且对称.结论 额叶脑回与髓突之间在冠状面上有规律可寻,影像学上可以通过髓突在冠状面上定位额叶脑回.%Objective To explore the corresponding rules between neural process and frontal lobe gyri and provide anatomic basis for locating frontal lobe gyri by neural process. Methods 20 normal cadaver heads were transected into brain slices with thickness of 6 mm after dyeing frontal lobe gyri. Typical planes were observed,while the correspondence between neural process and frontal lobe gyri on coronal sec-tions were analyzed and summarized. Results There was 1 or 2 processes for almost frontal lobe gyri,with the direction of neural process in different coronal sections being unchanged and symmetric. Conclusions The corresponding rules between neural processes and frontal lobe gyri may be obtained and the frontal lobe gyri on coronal sections may be located through neural processes.
