GENERAL HISTOLOGY

Detailed explanation-1: -As the name microglia suggests, these cells are small-the smallest of all the neuroglia. Microglia nuclei are typically oval-shaped, and projecting out from their cell bodies are slender elongated processes that enable the cells to move via chemotaxis (movement along a chemical gradient).

Detailed explanation-2: -Abstract. Microglia are the resident immune cells of the CNS. In the steady state, microglia are constantly surveilling their environment and facilitating the maintenance of synapses. These cells are characterized by a small cell body with fine, ramified processes and low expression of surface antigens.

Detailed explanation-3: -Microglia are a type of neuroglia (glial cell) located throughout the brain and spinal cord. Microglia account for about 10-15% of cells found within the brain. As the resident macrophage cells, they act as the first and main form of active immune defense in the central nervous system (CNS).
