Questions: Multiple Choice Question Which cells of the central nervous system can absorb stray neurotransmitters? Astrocytes Schwann cells Microglia Oligodendrocytes

The answer is the first one (Astrocytes): the original text in the question...

Explanation for each option:

1. Astrocytes: These are star-shaped glial cells in the central nervous system (CNS) that play a crucial role in maintaining the extracellular environment, including the absorption of stray neurotransmitters. They help in regulating the concentration of neurotransmitters in the synaptic cleft, thus preventing excessive stimulation or inhibition of neurons.

2. Schwann cells: These cells are part of the peripheral nervous system (PNS) and are responsible for the myelination of peripheral nerves. They do not absorb stray neurotransmitters in the CNS.

3. Microglia: These are the resident immune cells of the CNS and are primarily involved in immune defense and the removal of debris. They do not primarily function to absorb stray neurotransmitters.

4. Oligodendrocytes: These cells are responsible for the myelination of neurons in the CNS. Like Schwann cells, their primary function is not the absorption of stray neurotransmitters.

Summary: Astrocytes are the cells in the central nervous system that can absorb stray neurotransmitters, helping to maintain the balance of neurotransmitter levels in the synaptic cleft.
