Neuroglia

Neuroglia, also known as glial cells, are the supportive cells of the nervous system. They help maintain the environment around neurons, provide structural support, and assist with functions like nutrient delivery and waste removal. Unlike neurons, they do not transmit electrical signals but are essential for proper nerve function and health. There are different types of neuroglia, such as astrocytes, which support blood flow and chemical balance; oligodendrocytes and Schwann cells, which form the protective myelin sheaths around nerve fibers; and microglia, which act as immune cells. Together, they ensure the nervous system operates smoothly.
