Subarachnoid Space

The space where cerebrospinal fluid runs through.

Arachnoid Mater

The blue tissue that lies above the pia mater in the meningeal layers.

Subdural Space

The space found between the arachnoid mater and the dura mater.

Epidural Space

Space that contains fat and blood vessels, located outside the dura mater.

Dorsal Root Ganglion

Collection of unipolar neurons that transmit sensory information to the spinal cord.
