Question

Quizplus · Accepted Answer

The subarachnoid space contains a delicate network of collagen and elastin fibers through which cerebrospinal fluid circulates. The epidural space is a potential space between the dura mater and the vertebral column. The dural sinus is a channel between the layers of the dura mater that allows venous blood to drain from the brain. Arachnoid villi are structures in the subarachnoid space that allow cerebrospinal fluid to be reabsorbed into the venous circulation. The pia mater is a thin membrane that covers the surface of the brain and spinal cord.
