The concentration of ions in the chemical environment surrounding the neurons must be tightly regulated for neurons to function properly. Which of the following cells is most responsible for this?
A) astrocytes
B) satellite cells
C) Schwann cells
D) oligodendrocytes

Question

Quizplus · Accepted Answer

Astrocytes are responsible for regulating the chemical environment surrounding neurons, including the concentration of ions. They do this by taking up excess ions and releasing them as needed. Satellite cells are found in peripheral ganglia and support neurons, but do not play a role in ion regulation. Schwann cells and oligodendrocytes produce myelin around axons and do not have a direct role in regulating ion concentration.
