Astrocytes are star shaped glial cells because of cytoplasmic processes that extend from the cell body.

They play a role in regulating the extracellular composition of brain fluid. They release chemicals that promote the formation of tight junctions between the endothelial cells of capillaries.

They are insulating cells that cover the neurons. Other wise there will be short circuits in your brain.

The astrocytes differ from schawann cells becuase they provide nutrition and support fo neurons instead of just providing insulation like schwann cells.

Astrocytes, oligodendrocytes, microglia and ependymal cells.

Neither--these are both glial cells, cells that help and support neurons

Yes, astrocytes are glial cells that are involved in blood flow and regulation of neuron external chemical environment
