The scar tissue generated in the brain by _______ cells acts to impede the regrowth of nerve cells.
A) astrocytes
B) microglia
C) Schwann cells
D) axon terminals
E) phagocytes

Question

Quizplus · Accepted Answer

Astrocytes are glial cells that proliferate and generate scar tissue in response to injury or disease in the brain. This scar tissue can act as a barrier to the regrowth of nerve cells, contributing to the formation of permanent brain damage. Microglia and phagocytes are also glial cells that play a role in the immune response of the brain, but they are not typically associated with scar tissue formation. Schwann cells are a type of glial cell that plays a role in the regeneration of nerve cells in the peripheral nervous system, but not in the central nervous system. Axon terminals are structures at the ends of nerve cells that transmit signals to other cells, but they do not generate scar tissue.
