Neuroglia interact with neurons in several ways to ensure the proper functioning of the nervous system:
Synaptic Support: Astrocytes regulate neurotransmitter levels at synapses, preventing excitotoxicity and maintaining synaptic transmission. Nutrient Provision: Glial cells supply neurons with essential nutrients and remove waste products. Signal Modulation: Glial cells can modulate synaptic transmission and plasticity, influencing learning and memory processes. Myelination: Oligodendrocytes and Schwann cells myelinate axons, which is crucial for the fast transmission of action potentials.
