The concentration neurotransmitters in the fluid of the synaptic cleft must be tightly regulated for neurons to function properly.Which of the following cells is most responsible for aiding in this regulation?
A) satellite cells
B) astrocytes
C) Schwann cells
D) oligodendrocytes

Question

Quizplus · Accepted Answer

Astrocytes are responsible for aiding in the regulation of the concentration of neurotransmitters in the synaptic cleft. They take up excess neurotransmitter molecules and release them back into the synapse when needed. Satellite cells are found in ganglia and provide support to neurons. Schwann cells and oligodendrocytes are responsible for myelination of axons in the peripheral nervous system and central nervous system, respectively, and do not have a direct role in the regulation of neurotransmitter concentration in the synaptic cleft.
