Law enforcement officials surveyed nationwide reported a full 30 percent of gang-related crime in their jurisdiction was committed with firearms while 65 jurisdictions nationwide reported gang-related offenses carried out using firearms accounted for at least 95 percent of crime in their areas.
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.
Star-shaped glial cells in the CNS are collectively known as astrocytes. 'Astro' implies 'star' and 'cyte' refers to 'cell'. Hence, we get 'astrocyte': a star-shaped cell. These glial cells are responsible for a lot of important things in the central nervous system; most notably, they are part of the blood-brain barrier. Tiny little feet leave the astrocyte and help to encircle the vessels that make up the blood-brain barrier, which is a barrier that helps to prevent undesirable substances from entering the brain via blood vessels.
