The pia and arachnoid mater are also called leptomeninges.

软和蛛网也可以合称柔。

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

后两者，蛛网和软，合称柔。

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

层在蛛网之上，这两层中间腔隙叫做下隙。

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

前两者，即软和蛛网之间，叫作蛛网下隙；蛛网下隙里含有脊液，简称CSF。

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

下出血血液积聚在蛛网和层之间。

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；中间一层叫做蛛网；最外面一层叫做。

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.

外层叫，中间层叫蛛网，层则叫软。

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.

最一层叫软，中间一层叫做蛛网，最外面一层叫。

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，过下隙，穿过层，使血液回流至两层中间静脉窦中。

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.

流入第四室后，脊液进入蛛网下腔，即蛛网和软间隙；蛛网和软位于层，同时覆盖、保护大和脊髓。
