The functioning cell of the central nervous system is the neuron, which sends and receives signals to communicate information. Neurons are the fundamental building blocks of the CNS and engage in complex processes to relay messages throughout the body. Specialized cells of the nervous system are glial cells, or neuroglia, which provide support, protection, and nourishment to neurons. These cells play crucial roles in maintaining homeostasis, forming myelin, and aiding in the repair of neurons after injury, showcasing their importance beyond just structural support.
