摘　　要：目的探索端脑冠状面上中央前、后回与髓突的对应规律。方法选20例正常人脑标本,用广告颜料对各脑回染以不同颜色,作垂直于眦耳线、层厚6 mm的冠状脑切片。选取其中典型层面,通过染色确认中央前、后回,观察对应髓突的数目和方向。结果在所选取的3个典型层面上,中央前、后回对应1支髓突最常见。左侧中央前回所对应髓突分别位于10点和2点方向,右侧中央前回所对应髓突位于12点和2点方向。左侧中央后回所对应髓突分别位于11至11点半、11至12点和9至9点半方向,右侧中央后回所对应的髓突分别位于12至1点、1点半和2点半方向。结论端脑冠状切面上,中央前、后回所对应的髓突在数目和方向上是固定的。Objective To study the correspondence between medullary processes and pre-and post-central gyri on coronal sections of cerebrum.Methods The gyri of 20 normal human brain specimens were stained with poster paints,and then transected into 6 mm brain slices perpendicular to canthomeatal line.Number and orientation of medullary processes corresponding to pre-and post-central gyri were observed on the typical planes.Results One medullary process corresponding to pre-and post-central gyri was most common on the 3 typical planes.The medullary processes corresponding to left and right pre-central gyri were located at 10 and 2 o＇clock,and at 12 and 2 o＇clock,respectively.However,the medullary processes corresponding to left and right post-central gyri were located at 11-11：30,11-12,and 9-9：30 o＇clock,and at 12-1,1：30,and 2：30 o＇clock,respectively.Conclusion Number and orientation of medullary processes are invariably corresponding to preand post-central gyri on coronal sections of cerebrum.2 o＇clock direction
