What does neuroglia mean?
Neuroglia is the specialized supporting tissue of the nervous system. Its cells, collectively called glia, surround and protect neurons while supplying them with nutrients, helping maintain their environment, and contributing to repair after injury. The word comes from the Greek roots for 'nerve' and 'glue,' an apt description of the tissue's structural role. Neuroglia is especially associated with the brain and spinal cord, where glial cells include astrocytes, oligodendrocytes, and microglia. Although often described as the nervous system's 'glue,' neuroglia is not merely passive support: glial cells actively influence signaling, metabolism, development, and responses to disease. The term is mainly used in medicine, neuroscience, and biology, with 'glia' serving as the more concise everyday scientific form.
nounNeuroglia is the supporting tissue of the nervous system, consisting of cells that protect, nourish, and provide structural support for neurons. The term is also used collectively for this tissue.
- The collective supporting tissue of the nervous system.
- The individual cells or cell population that supports and protects nerve cells, especially in the brain and spinal cord.
"Damage to the neuroglia can disrupt the communication between nerve cells."
"The researcher studied how neuroglia responds to injury in the brain."
"Astrocytes are among the most abundant cells in the neuroglia."
Usually used as a mass noun; the plural is uncommon and generally appears when referring to distinct populations or types of neuroglial tissue.
"The study compared the neuroglias found in different regions of the brain."
The name neuroglia literally means 'nerve glue': these cells hold the nervous system together while also supporting and protecting its neurons.

Etymology of neuroglia
The word combines the Greek neuron, meaning 'nerve,' with glia, meaning 'glue.' The compound was introduced in the 19th century as a name for the supporting tissue of the nervous system. Its etymological relatives include glia, glial, and glioma, all of which belong to the modern scientific vocabulary associated with glue-like or supporting tissue.

How neuroglia is actually used
The term is primarily used in technical and medical contexts. In modern usage, 'glia' is often more common than 'neuroglia,' and 'neuroglial' is the standard adjective.
