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.
Nervous tissue consists of two main types of cells: neurons and neuroglia. Nerve cells, or neurones (also written neurons). that move information around the body.Neuroglia are also known simply as glia and have various functions in support of nerve cells but. themselves.lia or Neuroglia are therefore sometimes referred to as the non-nervous cells of the nervous system. Their functions within the nervous system depend on the specific type of neuroglia: Types of Neuroglial Cell: 1  Astroglial Cell Astrocyte.
