What does Subdural mean?

"Subdural" refers to a location beneath the dura mater, which is the outermost layer of the protective membranes surrounding the brain and spinal cord. It is commonly used in medical contexts, particularly in relation to subdural hematomas, which are collections of blood that accumulate between the dura mater and the brain, often resulting from head injuries. This term helps specify the anatomical position of conditions or procedures involving the central nervous system.
