Results The data of this study showed that the superior nuchal line and inion is not always a reliable external anatomical mark to locate the transverse sinus and torcular herophili .

结果实验所收集的数据表明在定位横窦 下 缘 和 窦 汇 时，上项线及枕外隆凸尖不是一个可靠的 浅表解剖学标志。

Anatomic Study of Superficial Marks of Transverse Sinus and Torcular Herophili

横窦和窦 汇的浅表解剖学标志

Method : 5 cranium specimen . Study the drainage connection with other sinus and the split stream of torcular herophili after removal of the cranial roof .

方法：5具成人头颅标本，去除 颅盖，观察上 矢 状 窦 的 大体 解剖、 静脉 属 支、与其他静脉的 交通及窦 汇 处回流 方向。

Of the total 175 AGs 90 AGs were found in transverse sinus 77 in superior sagittal sinus 5 in straight sinus 2 in torcular Herophili 1 in inferior sagittal sinus .

66例共发现175个蛛网膜颗粒，其中 横窦90个，上矢状窦77个，直窦5 个， 窦 汇2 个，下矢状窦1 个。

Finally the sinuses were opened for direct observation of the chordae arachnoid granulations and torcular herophili using standard anatomical methods .

并纵行剖开 管腔，显微镜 下观察纤维索、蛛网膜颗粒及窦 汇 区解剖。
