Objective To explore the developmental rules of grooves in fetal cerebral parietal lobes,occipital lobes and lateral grooves so as to provide some reference materials in the study of the structures and functions of adult brains.Methods 89 body specimens at different gestational ages were collected and then fixed with 10% formalin.The brains of them were removed 3 months later.The emerging time,the length and the depth of grooves in occipital lobes,parietal lobes and lateral grooves were identified,and the developmental states of the cerebral grooves at different gestational ages were contrasted and further analysed.Results The emerging times of grooves in parietal lobes and occipital lobes differed greatly;postcentral sulcus began to appear in the 5th month and were well formed in the 8th month;parieto-occipital and serrated sulcus began to emerge in the 4th month and were fully formed in the 6th month;lateral sulci emerged the earliest and in the 4th month were fully formed.It has shown that the older the fetus was,the more the length extended,the depth and the curvature of the cerebral grooves more developed.It seemed that the cerebral grooves developed the most rapidly betwwen the 8th month and the 9th month.Conclusion The development of fetal cerebral occipital and parietal sulci are closely related to the gestational age and the developmental rules of defferent cerebral sulcus vary to some entent.

目的  探讨顶叶、枕叶脑沟及外侧沟的发育规律 ,为研究成人脑的结构和功能提供参考资料。方法  将收集到的 89具不同胎龄的标本经 10 %福尔马林固定 3个月后取脑 ,观测顶叶、枕叶各脑沟及外侧沟的出现时间、长度及深度 ,并对各胎龄组脑沟的发育情况进行对比分析。 结果  顶叶、枕叶脑沟出现时间差别较大 ,中央后沟从第 5月龄开始出现 ,至第 8月龄全部出现 ;顶枕沟和距状沟从第 4月龄开始出现 ,至第 6月全部出现 ;外侧沟出现最早 ,第 4月龄已全部出现。随胎龄增长 ,脑沟的长度增加 ,深度也加深 ,且弯曲度也越来越大 ,脑沟生长速度最快的时间在第 8~ 9月龄。结论  胎脑顶叶、枕叶脑沟的生长发育与胎龄有密切关系 ,且各脑沟的发育规律不尽相同。

Results:(1)On the section through the intercommisural line,the appearing rate of the parieto-occipital sulcus was 16.7% on the left side and 10% on the right;On the section of the sple-nium of corpus callosum appearing for the...

Results:(1)On the section through the intercommisural line,the appearing rate of the parieto-occipital sulcus was 16.7% on the left side and 10% on the right;On the section of the sple-nium of corpus callosum appearing for the first time, the appearing rate of the parieto-occipital sulcus was 93.3% on the left side and 90% on the right; Deep in the conjunction of the cingulate and lingual gyri was the cuneate gyrus. (2)On the section through the column of fornix and septum pellucidum,the parieto-occipital sulcus moved forward,its appearing rate was 100% on the left side and 93.3% on the right. It was 15.8 mm and 16.4 mm on left and right sides respectively. It had 1-3 branches. (3)On the section when theparieto-occipital sulcus disappeared,the superrior part of the semiovale center of the cerebral marrow appeared, with appearing rate 86.7% on the left and right;The cingulate gyrus would disappear and the paracentral lobule would appear. Conclusion;The parieto-occipital sulcus appears on the 1~2 sections between the intercommisural plane and the plane of the splenium of corpus callosum appearing for the first time, the appearing of the cuneate gyrus is the important signal. The parieto-occipital sulcus disappears on the 1-2 sections from the cingulate gyrus will disappear to the paracentral lobule will appear.

目的:为了探讨大脑顶枕沟在横断面上的准确定位。方法:选用正常成人头部标本30例,以AC-PC线为基线,获取4mm层厚的连续横断层MR图像和脑断层标本。在连续断层标本上对顶枕沟的断面表现进行跟踪观察、测量和统计。结果:1.在AC-PC线断面上,顶枕沟的出现率左侧为16.7%、右侧为10%;在胼胝体压部首次切及的断面上,顶枕沟位于扣带回峡的后方,其出现率左侧为93.3%、右侧为90%,在扣带回峡和舌回交界处的深面可见深埋的楔回。2.在切及穹窿柱和透明隔断面上,顶枕沟后移,位于大脑半球后部内侧缘前、中1/3交点附近,其出现率左侧为100%、右侧为93.3%,沟的平均深度左侧为15.8mm、右侧为16.4mm,沟内一般有1~3支分支。3.在顶枕沟即将消失的断面上,大脑半球髓质的半卵圆中心上部的出现率左侧、右侧均为86.7%,扣带回即将消失,中央旁小叶尚未出现。结论:顶枕沟出现在前后连合平面至胼胝体即将出现的1~2个断面上,扣带回峡后方楔回的出现是顶枕沟首次出现的重要信号;当大脑半球出现半卵圆中心上部时,从扣带回顶部出现到中...
