Subdural space
Subdural Space
The Subdural Space (pronunciation: /sʌbˈdjʊərəl speɪs/) is a potential space located between the Dura mater and the Arachnoid mater, two of the three Meninges that surround the Brain and Spinal cord.
Etymology
The term "Subdural" is derived from Latin, with "sub" meaning under and "dura" referring to the dura mater. Thus, "Subdural" literally means "under the dura mater".
Description
The Subdural Space is not a true space but a potential space, which means it is normally collapsed but can fill with fluid or blood under certain conditions, such as in the case of a Subdural hematoma. It contains a small amount of serous fluid which allows the dura mater and arachnoid mater to slide over each other.
