D
Ependymal cells
Verified step by step guidance1
Understand the role of neuroglial cells in the central nervous system (CNS). These cells support neurons in various ways, including structural support, nutrient supply, and immune defense.
Identify the main types of neuroglial cells in the CNS: oligodendrocytes, astrocytes, ependymal cells, and microglia.
Recall the specific functions of each type: oligodendrocytes produce myelin, astrocytes maintain the blood-brain barrier and regulate the extracellular environment, ependymal cells line the ventricles and produce cerebrospinal fluid.
Focus on microglia, which are specialized immune cells in the CNS. They act as the brain's resident macrophages and have phagocytic properties, meaning they can engulf and digest cellular debris and pathogens.
Conclude that the neuroglial cell with phagocytic properties as part of the innate immune response in the CNS is the microglia.
