D)reduces injury to surrounding tissue

Question

Quizplus · Accepted Answer

Reactive astrocytosis is a process where astrocytes (a type of glial cell) in the central nervous system become activated in response to injury or disease. The activated astrocytes proliferate and form a scar around the injury site, which blocks off the damaged area and prevents further injury to surrounding tissue (A and D). However, the scar tissue that is formed can limit regeneration of nerve cells in the damaged area, leading to permanent damage (B). Reactive astrocytosis does not cause the spread of inflammation, as this is typically a function of the immune system rather than the glial cells.
