corpus callosum在生物学中指的是“胼胝体”,它是大脑中连接左右半球的重要结构。以下是对胼胝体的详细解释: 一、结构特点 位置:胼胝体位于大脑纵裂底部,呈宽带状。 构成:由约2亿至2.5亿条神经纤维构成,这些纤维从大脑中线向两侧延伸,穿过半卵圆中心,投射至各脑区皮层,形成辐射状分布。 分部:根据连接区域的不同,...
胼胝体(corpus callosum,cc)位于大脑半球纵裂的底部,连接左右两侧大脑半球的横行纤维束,是大脑半球中最大的联合纤维。 这些神经纤维在两半球中间形成弧形板,其后端叫压部(spkinum),中间叫体部(body),前方弯曲部叫膝部(genu),膝向下弯曲变薄...

GA. On fetal MRI, the corpus callosum appears after 20weeks as a curvilinear T2hypointense structure lining the superior margin of the CSP, and it slightly increases in length and thickness during pregnancy (Fig. 17.6). Fetal MRI has been shown to be an important complementary study to ultras...
but the back section is preserved. This allows the hemispheres to continue sharing visual information. If this does not control the serious seizures, the remainder of the corpus callosum can be cut in a second operation. After the corpus callosum is cut, the dura and bone are fixed back into...
