The internal layer of the dura mater lies above the arachnoid mater and the two are separated by the subdural space.

硬脑膜的内层在蛛网膜之上，这两层中间的腔叫做硬膜下。

The outer membrane is the dura mater, which forms the meningeal folds, such as falx cerebri and tentorium.

最外层的硬脑膜可以形成脑膜折结构，比如大脑镰和小脑幕。

These veins travel through the arachnoid mater, pass through the subdural space and penetrate the inner layer of the dura mater to drain into the dural venous sinuses located between the two layers of the dura mater.

这穿过蛛网膜，过硬膜下，穿过硬脑膜内层，使血液回流至两层硬脑膜中间的窦中。

Once all the bleeding is stopped, we essentially then close the covering on the brain, which is called the dura, fix the bone flap back to the skull, then we close the scalp, then we get lunch.

一旦所有的出血都停止了，我们会然后关闭大脑上的覆盖物，也就是所谓的硬脑膜，将骨瓣固定回头骨，然后我们关闭头皮，然后去吃午饭。
