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

者，蛛网和软脑，合称柔脑。

The pia and arachnoid mater are also called leptomeninges.

软脑和蛛网也可以合称柔脑。

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

前者，即软脑和蛛网之间，叫作蛛网隙；蛛网隙里含有脑脊液，简称CSF。

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

出血的血液积聚在蛛网和脑内层之间。

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

脑的内层在蛛网之上，这层中间的腔隙叫做隙。

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.

脑的外层叫脑，中间层叫蛛网，内层则叫软脑。

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.

最内一层脑叫软脑，中间一层叫做蛛网，最外面一层叫脑。

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；中间一层叫做蛛网；最外面一层叫做脑。

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，过隙，穿过脑内层，使血液回流至层脑中间的静脉窦中。

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，脑脊液进入蛛网腔，即蛛网和软脑的间隙；蛛网和软脑位于脑内层，同时覆盖、保护大脑和脊髓。
