Syrinx and Glial Scar | © Edmond Alexander
A syrinx is a fluid-filled cavity within the spinal cord subsequent to glial scar formation. The glial scar is a reactive cellular process involving astrogliosis that occurs after injury to the Central Nervous System. Although the glial scar does a good job at controlling and suppressing further physical damage, it does have important caveats to neuroregeneration. Particularly, many neuro-developmental inhibitor molecules are secreted by the cells within the scar that prevent complete physical and functional recovery of the central nervous system.
