Which cells in the nervous system provide support, nourishment, and protection for neurons?

• A. Glial cells
• B. Neurons
• C. Oligodendrocytes
• D. Astrocytes

Answer: (A)

Glial cells are the cells that provide support, nourishment, and protection for neurons. They don’t transmit signals themselves, but they create and maintain the environment neurons need to function. Astrocytes, for example, help shuttle nutrients from the blood to neurons and keep the chemical surroundings stable. Oligodendrocytes in the CNS wrap axons with myelin to speed signal transmission, and microglia act as the brain’s immune defenders. Together, these glial cells give neurons the structural support, metabolic backing, and protective barriers essential for proper neural functioning. Neurons handle signaling, but glial cells supply the supportive context that makes signaling possible, so this broad category best fits the described roles.
