GlossaryGlial cells (Neuroglia)

non-neuronal cells supporting and protecting neurons in the nervous system

Glial cells, also known as neuroglia or simply glia, are non-neuronal cells in the central and peripheral nervous systems that provide support and protection for neurons. They play crucial roles in maintaining homeostasis, forming myelin, and providing support and protection for the brain's neurons, as well as participating in signal transmission and repair processes after injury.
