Which of the Following is NOT True of Reactive Astrocytosis

Question

Which of the following is NOT true of reactive astrocytosis?
A) Injury site is blocked off
B) Scars limit regeneration
C) Causes the spread of inflammation
D) Reduces injury to surrounding tissue

Accepted Answer

Reactive astrocytosis is a process where astrocytes (a type of glial cell in the brain) proliferate in response to injury. It involves the formation of a glial scar to block off the injury site (A), which can limit regeneration (B) and help reduce further injury to surrounding tissue (D). However, it does not cause the spread of inflammation; rather, it is a response to injury and inflammation.
