Phrases with «glial scar»

A "glial scar" refers to a type of scar tissue that forms in the brain or spinal cord as a result of injury or disease. Glia are specialized cells in the nervous system that help support and protect neurons. When the brain or spinal cord is damaged, glial cells form this scar to seal off the affected area and prevent further injury. However, this scar can also hinder the regeneration of neurons, making it difficult for the nervous system to fully recover. Full definition
