A) pia mater
B) subarachnoid space
C) subdural space
D) epidural space

Accepted Answer

The space within the meninges of the spinal cord that contains the cerebrospinal fluid is called the subarachnoid space. The pia mater is the innermost layer of the meninges that directly covers the surface of the spinal cord. The subdural space is the space between the dura mater (outermost layer of the meninges) and the arachnoid mater (middle layer of the meninges). The epidural space is the space outside the dura mater, between the dura mater and the vertebral column.
