What does glia mean?
Glia, also known as neuroglia or glial cells, are non-neuronal cells that provide essential support and maintenance functions for neurons in the brain and spinal cord. They play a crucial role in regulating the environment around neurons, supplying them with oxygen and nutrients, and removing waste products. Glia are a vital component of the central nervous system, and their dysfunction has been implicated in various neurological disorders. The term glia is derived from the Greek word for 'glue', reflecting their role in holding neurons together and providing a supportive matrix. Understanding glia is important for understanding the complex interactions between neurons and their environment.
