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

后者，蛛网膜和软膜，合膜。

The pia and arachnoid mater are also called leptomeninges.

软膜和蛛网膜也可以合膜。

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

前者，即软膜和蛛网膜之间，叫作蛛网膜；蛛网膜含有脊液，简CSF。

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

硬膜出血的血液积聚在蛛网膜和硬膜内层之间。

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

硬膜的内层在蛛网膜之上，这层中间的腔叫做硬膜。

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.

膜的外层叫硬膜，中间层叫蛛网膜，内层则叫软膜。

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.

最内一层膜叫软膜，中间一层叫做蛛网膜，最外面一层叫硬膜。

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.

最面一层叫做软膜；中间一层叫做蛛网膜；最外面一层叫做硬膜。

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.

这些静脉穿过蛛网膜，经过硬膜，穿过硬膜内层，使血液回流至层硬膜中间的静脉窦中。

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.

流入第四室后，脊液进入蛛网膜腔，即蛛网膜和软膜的间；蛛网膜和软膜位于膜内层，同时覆盖、保护大和脊髓。
