Explanation:
Detailed explanation-1: -Microglia, the resident macrophages of the central nervous system, rapidly activate in nearly all kinds of neurological diseases. These activated microglia become highly motile, secreting inflammatory cytokines, migrating to the lesion area, and phagocytosing cell debris or damaged neurons.
Detailed explanation-2: -In the central nervous system (CNS), microglia are considered to be the major phagocytes.
Detailed explanation-3: -Microglia. Microglia phagocytose and remove foreign or damaged material, cells, or organisms. They are small, relatively sparse cells. They act as the brain’s resident cleanup squad by phagocytosing apoptotic cells, plaques, and pathogens.
