Astroglia refers to a group of cells in the central nervous system that provide support and protection to neurons. These cells are a type of glial cell and are distinct from neurons, which are primarily responsible for transmitting nerve impulses. Astroglia are the most abundant type of glial cell in the brain and spinal cord.

There are several types of astroglia, each with specialized functions. Astrocytes, a major subtype, play a crucial role in maintaining the blood-brain barrier, regulating the chemical environment around neurons, and providing nutrients. They also help in the formation and repair of synapses, the junctions between neurons where communication occurs. Another type, ependymal cells, line the ventricles of the brain and central canal of the spinal cord, producing and circulating cerebrospinal fluid.

Astroglia are essential for the proper functioning of the nervous system. They contribute to neural development, synaptic plasticity, and the overall homeostasis of the brain. When damaged or dysfunctional, astroglia can contribute to neurological disorders. Research into astroglia continues to uncover their complex roles in both health and disease.
