Q

name the five glial cells and their functions and contrast these with neuronal structure and function

A

astrocytes - provide the brain cells with glucose, ependymal cells - some make the csf fluid, is likened to the epithelial cell, microglia - immune system type of neuron cells, oligodendrocytes - neuron myelinates neuron in the cns, schwann cell - myelinates the neuron in the pns
