GENERAL HISTOLOGY

Detailed explanation-1: -The epidural space is a tissue plane between the dura mater, covering the spinal nerve and dural sac, and the periosteum and ligaments within the vertebral canal and the intervertebral foramen (IVF).

Detailed explanation-2: -The space between the dura mater and wall of the vertebral canal is called the epidural space. The epidural space contains fat, small blood vessels, and spinal nerve roots. The epidural space helps absorb shock and keep the spinal cord in place.

Detailed explanation-3: -Spinal Meninges The epidural space lies between the spinal dura mater and the periosteum of the vertebral canal. The subarachnoid space extends as a narrow slit between the arachnoid and the pia mater. The inner electron-dense cell layer of the arachnoid appears occluded and opens only around the spinal roots.

Detailed explanation-4: -Epidural Space Definition The epidural space is the area between the dura mater (a membrane) and the vertebral wall, containing fat and small blood vessels. The space is located just outside the dural sac which surrounds the nerve roots and is filled with cerebrospinal fluid.

Detailed explanation-5: -Spinal epidural space is a real anatomic space located outside the dura mater and within the spinal canal extending from foramen magnum to sacrum. Important contents of this space are epidural fat, spinal nerves, epidural veins and arteries.
