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) satellite cells
B) astrocytes
C) Schwann cells
D) oligodendrocytes

Question

Quizplus · Accepted Answer

Astrocytes are known to play a crucial role in regulating the chemical environment surrounding neurons, including the concentration of ions such as sodium, potassium, and calcium. They provide structural, metabolic, and functional support to neurons and are in close contact with them, allowing them to exchange signals and maintain homeostasis. Satellite cells are associated with sensory neurons, Schwann cells are responsible for myelination in the peripheral nervous system, and oligodendrocytes perform a similar function in the central nervous system, but none of these cells are primarily responsible for regulating ion concentration.
