Which statement best describes the function of neuroglia?

Which statement best describes the function of neuroglia?

• A. Protect, support, and repair neural tissue
• B. Transmit impulses between neurons
• C. Contract to move skeleton
• D. Produce blood cells

Answer: (A)

Neuroglia are the non-neuronal cells in the nervous system that provide support and maintenance for neurons. They protect, support, and repair neural tissue by offering metabolic support, regulating the extracellular environment, clearing debris after injury, forming the blood-brain barrier, and supplying myelin to insulate neurons and speed up signal conduction. They don’t transmit impulses themselves—that role belongs to neurons. The other options describe muscle contraction or blood cell production, which are functions of other tissues. So the statement that best fits neuroglia is that they protect, support, and repair neural tissue.
