These last two, the arachnoid and pia maters, are the leptomeninges.

后者，膜和软脑膜，合称柔脑膜。

The pia and arachnoid mater are also called leptomeninges.

软脑膜和膜也可以合称柔脑膜。

These first two, the pia and arachnoid maters, form the subarachnoid space, which houses the cerebrospinal fluid, or CSF.

前者，即软脑膜和膜之间，叫作膜下；膜下里含有脑脊液，简称CSF。

The blood in a subdural hemorrhage is located between the arachnoid mater and the inner layer of the dura mater.

硬膜下出血的血液积聚在膜和硬脑膜内层之间。

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

硬脑膜的内层在膜之上，这层中间的腔叫做硬膜下。

The outer layer of the meninges is the dura mater, the middle layer is the arachnoid mater, and the inner layer is the pia mater.

脑膜的外层叫硬脑膜，中间层叫膜，内层则叫软脑膜。

The inner layer of the meninges is the pia mater, the middle layer is the arachnoid mater and the outer layer is the dura mater.

最内一层脑膜叫软脑膜，中间一层叫做膜，最外面一层叫硬脑膜。

The inner layer of the meninges is the pia mater; the middle layer is the arachnoid mater; and the outer layer is the dura mater.

最里面一层叫做软脑膜；中间一层叫做膜；最外面一层叫做硬脑膜。

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.

这些静脉穿过膜，过硬膜下，穿过硬脑膜内层，使血液回流至层硬脑膜中间的静脉窦中。

After the fourth ventricle, the cerebrospinal fluid enters the subarachnoid space, which is the space between the arachnoid and pia mater, two of the inner linings of the meninges which cover and protect both the brain and the spine.

流入第四脑室后，脑脊液进入膜下腔，即膜和软脑膜的间；膜和软脑膜位于脑膜内层，同时覆盖、保护大脑和脊髓。
