Neurons in the CNS Have Less Chance of Regenerating for All

Question

Neurons in the CNS have less chance of regenerating for all of the following reasons except:
A)there is no neurolemma in cells of the CNS.
B)astrocytes fill in the path of regrowth.
C)microglia lay down scar tissue.
D)All of these lessen the chance of healing in the CNS.

Accepted Answer

Microglia do not lay down scar tissue; instead, they act as immune cells in the CNS, clearing debris and dead cells. Scar tissue formation is primarily associated with astrocytes.
