NEUROGLIAL CELLS Meaning and
Definition
-
Neuroglial cells, also known as glial cells, are a specialized type of non-neuronal cells found in the central nervous system (CNS) and peripheral nervous system (PNS). They provide crucial support and maintenance functions for neurons, which are the primary functional cells of the nervous system.
Unlike neurons, neuroglial cells do not conduct electrical impulses or transmit information. Instead, they play essential roles in providing structural support, insulation, and protection to neurons. They also participate in various physiological processes such as signaling, metabolism, and immune defense in the nervous system.
There are several types of neuroglial cells, each with distinct functions. Astrocytes are the most abundant type and are involved in regulating the concentration of ions, neurotransmitters, and nutrients around neurons. They also provide physical support and regulate blood flow to the brain. Oligodendrocytes in the CNS and Schwann cells in the PNS produce myelin, a fatty substance that coats the axons of neurons and facilitates faster transmission of electrical signals. Microglia play a crucial role in the immune defense of the CNS, protecting the brain from pathogens and clearing dead cells and debris.
Overall, neuroglial cells form an intricate network that supports, protects, and maintains the health of neurons. Their functions are essential for the proper functioning of the nervous system and are crucial for overall brain function and cognitive abilities.

Etymology of NEUROGLIAL CELLS
The word "neuroglia" originates from the Greek terms "neuron" meaning "nerve" and "glia" meaning "glue". The term was first coined by the German anatomist Rudolf Virchow in the mid-19th century. Virchow used this term to describe the supportive cells in the nervous system that were responsible for providing structural support and maintaining the health of neurons. Over time, these cells became known as "neuroglial cells", reflecting their function in supporting and protecting nerve cells, even though "neuroglia" itself is technically a collective term for multiple types of glial cells in the nervous system.
