This is a correct answer. Glia cells are supportive cells that provide insulation, protection, nutrition, and regulation for neurons. One type of glia cells, called oligodendrocytes, produce myelin that insulates nerve fibers and increases the speed of electrical impulses.
This is an incorrect answer. Glia cells do not transmit electrical impulses along nerve fibers. This is the function of neurons, which are the primary cells of the nervous system.
This is an incorrect answer. Glia cells do not secrete neurotransmitters that communicate with other cells. This is also the function of neurons, which release neurotransmitters at the synapses to transmit signals to other neurons, muscles, or glands.
This is an incorrect answer. Glia cells do not destroy pathogens and foreign substances in the nervous system. This is the function of microglia, which are a type of immune cells that reside in the nervous system and act as macrophages.
