Definition:
A neuroglial cell (often just called a "glial cell") is a type of cell found in the brain and nervous system. These cells are not nerve cells (neurons) but play an important role in supporting and protecting neurons, which are the cells that send and receive signals in the nervous system.
In more advanced discussions, you might hear about different types of neuroglial cells, such as: - Astrocytes: They provide structural support and help regulate blood flow in the brain. - Oligodendrocytes: These cells produce the myelin sheath that insulates nerve fibers. - Microglia: These are the immune cells of the brain, helping to protect against infection and injury.
While "neuroglial cell" has a specific meaning in the context of biology and neuroscience, outside of this context, the individual words "neuro" and "glial" might not hold significant meaning on their own for non-specialists.
There are no specific idioms or phrasal verbs directly related to "neuroglial cell," as it is a technical term. However, you may come across phrases in scientific literature that emphasize the supportive role of these cells, such as "supporting roles" in the nervous system.
A neuroglial cell is a vital part of the nervous system that supports and protects neurons.
