Choose the correct match of glial cell type and function.
A) astrocytes-promote blood flow and regulate ion concentrations
B) oligodendrocytes-produce the myelin sheaths of myelinated neurons in the peripheral nervous system
C) radial glia-the source of immunoprotection against pathogens
D) Schwann cells-provide nutritional support to non-myelinated neurons

Question

Quizplus · Accepted Answer

Astrocytes are known to promote blood flow to neurons and regulate ion concentrations in extracellular fluid. Oligodendrocytes are responsible for producing myelin sheaths in the CNS, not the PNS. Radial glia play an important role in guiding migration of neurons during embryonic development, they are not involved in immune protection. Schwann cells are responsible for producing myelin sheaths in the PNS and also aid in regenerating damaged axons.
