Neuroglia - English Definition & Meaning

Definition

Neuroglia, also known as glial cells, are support cells in the nervous system. They don't transmit signals like neurons, but they provide crucial support and protection. Think of them as the unsung heroes of the brain, maintaining a healthy environment for neurons to function properly. They help neurons stay in place, supply nutrients, remove waste, and fight off infections. Unlike neurons, neuroglia can divide and multiply throughout life. They're like the maintenance crew keeping the neural machinery running smoothly.

Etymology

'Neuroglia' comes from the Greek 'neuron' (nerve) and 'glia' (glue). It literally means 'nerve glue,' reflecting the early belief that these cells simply held the nervous system together. However, we now know that neuroglia play a much more active and diverse role. The term reflects the historical understanding of their function. The etymology highlights their supportive, though more complex, role.
