Astrocytes (Astro from Greek astron = star and cyte from Greek kyttaron = cell), also known collectively as astroglia, are characteristic star-shaped glial cells in the brain and spinal cord. The proportion of astrocytes in the brain is not well defined.Depending on the counting technique used, studies have found that the astrocyte proportion varies by region and ranges from 20% to 40% of all glia. Astrocytes get their name because they are star-shaped. 2  They are the most abundant glial cells in the brain that are closely associated with neuronal synapses. 3  They regulate the transmission of electrical impulses within the brain.
