So a subdural hemorrhage is when there's bleeding below the dura mater.

所以" Subdural Hemorrhage" 指脑部血管破裂出血至硬膜下隙。

The outer membrane is the dura mater, which forms the meningeal folds, such as falx cerebri and tentorium.

最外层的硬脑膜可以形成脑膜折叠结构，比如大脑镰和小脑幕。

The external layer of the dura mater adheres to the inner surface of the skull.

硬脑膜外层则紧贴在颅骨内面。

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

硬脑膜的内层在蛛网膜之上，这两层中间的腔隙叫做硬膜下隙。

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蛛网膜和硬脑膜内层之间。

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.

最内一层脑膜叫软脑膜，中间一层叫做蛛网膜，最外面一层叫硬脑膜。

Between the external layer of the dura mater and the inner surface of the skull, there are arteries that supply the meninges.

在硬脑膜外层和颅骨内面之间，有脑膜的供血动脉。

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，中间层叫蛛网膜，内层则叫软脑膜。

In contrast to that, epidural hemorrhages cause blood to build up between the outer layer of the dura mater and the skull.

作为对比，硬膜外出血的血液则积聚在硬脑膜外层和颅骨之间。

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.

最里面一层叫做软脑膜；中间一层叫做蛛网膜；最外面一层叫做硬脑膜。

These two layers of the dura mater travel together, but at certain spots, the internal layer of the dura mater separates from the external one to form the meningeal folds.

两层硬脑膜共同运动，但在某些地方，硬脑膜内层和外层分开，形成一些脑膜折叠。

Since the outer layer of the dura mater adheres tightly to the skull at sutures, epidural hematoma don't cross suture lines, and they push on the brain, forming a bi-convex shape.

由于硬脑膜外层与颅骨在颅缝处紧紧相贴，硬膜外出血不会跨过颅缝，且血肿会压迫大脑，形成双凸镜形。

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，经过硬膜下隙，穿过硬脑膜内层，使血液回流至两层硬脑膜中间的静脉窦中。
