Epidural administration involves delivery into which anatomical space?

Explanation:
Epidural administration delivers drugs into the epidural space, a potential space between the dura mater and the walls of the vertebral canal. This space contains fat and a venous plexus around the nerve roots as they emerge from the spinal cord, allowing anesthetic to block those nerves to produce targeted regional anesthesia. It is not the intrathecal/subarachnoid space, which houses cerebrospinal fluid inside the dural sac, nor is it a vein or muscle tissue.
