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

后者，蛛和软，合称柔。

The pia and arachnoid mater are also called leptomeninges.

软和蛛也可以合称柔。

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

前者，即软和蛛之间，叫作蛛隙；蛛隙里含有脊液，简称CSF。

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

硬出血的血液积聚在蛛和硬内层之间。

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

硬的内层在蛛之上，这层中间的腔隙叫做硬隙。

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.

的外层叫硬，中间层叫蛛，内层则叫软。

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.

最内一层叫软，中间一层叫做蛛，最外面一层叫硬。

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；最外面一层叫做硬。

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，经过硬隙，穿过硬内层，使血液回流至层硬中间的静脉窦中。

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.

流入第四室后，脊液进入蛛腔，即蛛和软的间隙；蛛和软位于内层，同时覆盖、保护大和脊髓。
