Neuroglia ( I ) Astrocyte  Swell  Reactive Astrogliosis: Undergo hyperplasia and hypertrophy, produce a dense network of processes and forming of glial scar.  (Glial scar: astrocytes do not produce collagen. It is made up predominantly of cytoplasmic processes, with little or no extracellular protein)  Gemistocytic Astrocyte: It is often associated with increased synthesis of glial fibrillary acidic protein (GFAP)
