Rationale: Glial cells, known as astrocytes, participate in cellular signaling with other astrocytes, neurons, and cells such as vascular smooth muscle. Glial cells also play an important role in phagocytosis and CNS development. Oligodendrocytes and Schwann cells aid in the propagation of action potentials generated by the neuron. Macroglial cells clean the extracellular environment; however, hyperactivity of these and other glial cells may result in neurologic damage.
