Neuroglia (also called glial cell of glia) are cells which main function is to support and protect neurons. Neuroglia cells provide neurons glucose, amino acids, and ions, change the rate of nerve signal propagation, change synaptic action, provide help during neuron development and after neural injury. The biggest difference between neurons and neuroglia cells is that neuroglia cells are not directly involved in synaptic interactions and electrical signaling, they also are smaller and they don't have axon and dendrites.
