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

膜的内在蛛网膜之上，这中间的腔隙叫做膜下隙。

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

最外的膜可以形成膜折结构，比如大镰和小幕。

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.

这些静脉穿过蛛网膜，过膜下隙，穿过膜内，使血液回流膜中间的静脉窦中。

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，我们会然后关闭大上的覆盖物，也就是所谓的膜，将骨瓣固定回头骨，然后我们关闭头皮，然后去吃午饭。
