Question

Glia cells play a supportive role to the neuron. A few of the functions of the glial cells include providing nutrition, maintaining homeostasis, stabilizing synapses, and myelinating axons. The glial cells are categorized as microglia and macroglia. Of these two cell types, which one plays an active and critical role in glutamatergic neurotransmission by providing a co-agonist required for glutamate receptor function?

	A.	microglial
	B.	macroglial

Answer 1

Answer Option A. Microglial

Option A is incorrect as the microglial type of cells play an active and important role in glutamatergic neurotransmission by providing a co-agonist required for glutamate receptor function. The expression of the glutamate in the neurotransmitter signalling in microglial glutamate has function as a major excitatory neurotransmitter as well as helps in providing the co-agonist for glutamate receptor functioning.

Option B is incorrect as the macroglial cells are not involved in the glutamatergic neurotransmission process and also does not have an impact with the glutamate receptor function.
