What type of cells provide support and protection to neurons?

• A. Neurons
• B. Neuroglia
• C. Dendrites
• D. Axons

Answer: (B)

Neuroglia are the cells that provide essential support and protection to neurons in the nervous system. They are non-neuronal cells that play a crucial role in maintaining the homeostasis of the neuronal environment, providing structural support, and facilitating the normal functioning of neurons. Neuroglial cells include various types such as astrocytes, oligodendrocytes, microglia, and ependymal cells, each fulfilling specific functions. For example, astrocytes help regulate blood flow and maintain the blood-brain barrier, while oligodendrocytes are responsible for the myelination of axons in the central nervous system, enhancing signal transmission. In contrast, neurons are the primary signaling cells of the nervous system, responsible for transmitting information through electrical impulses. Dendrites and axons are components of neurons; dendrites receive signals, while axons transmit them to other cells. However, they do not perform the supportive and protective roles that neuroglia do. Understanding the distinct functions of these cell types is key to grasping how the nervous system operates as a whole.
