NEUROGLIAL Meaning and
Definition
-
Neuroglial refers to something that relates to or is associated with neuroglia, which are non-neuronal cells in the central nervous system (CNS) that provide support and protection to neurons. Neuroglia, also known as glial cells, are crucial for maintaining the structural integrity and functionality of the CNS. They outnumber neurons in the brain and spinal cord, making up around 90% of the cells in the CNS.
The main types of neuroglia include astrocytes, oligodendrocytes, microglia, and ependymal cells. Astrocytes are star-shaped cells that play a vital role in maintaining the microenvironment for neuronal functioning, regulating blood flow, and participating in the repair process after injury. Oligodendrocytes produce myelin, a fatty substance that insulates the axons of neurons, enabling faster and efficient transmission of nerve impulses. Microglia serve as the immune cells of the CNS, protecting it from pathogens and removing damaged neurons and debris. Ependymal cells line the cavities of the brain and spinal cord, producing and circulating cerebrospinal fluid.
The prefix "neuro-" in neuroglial indicates the relationship of these cells with the nervous system, emphasizing their supportive and protective functions. Neuroglial cells not only maintain the physical framework of the CNS but also contribute to important processes like synapse formation, signal transmission, and immune response regulation. Their intricate interactions with neurons are essential for the proper functioning of the nervous system.
Common Misspellings for NEUROGLIAL
Etymology of NEUROGLIAL
The word "neuroglial" is derived from two Greek roots: "neuron" meaning "nerve" and "glia" meaning "glue". Neuroglia refers to the non-neuronal cells that support and protect the neurons in the nervous system. The term was coined by German anatomist Rudolf Virchow in the mid-19th century, who observed that these cells appeared to hold the neurons together like a glue. Hence, the word "neuroglial" combines the Greek roots to describe the glue-like supportive cells in the nervous system.
