The nervous system is an intricate network of organs, tissues, and nerves that coordinate the activities of the body. There are several synonyms for the nervous system, which include the neural system, the nerve network, the neuron system, the central nervous system (CNS), and the peripheral nervous system (PNS). The neural system refers to the network of cells, tissues, and nerves that communicate with one another to control the body's functions. The nerve network also refers to the interconnection of the nervous system's components. The neuron system describes the individual nerve cells (neurons) that transmit information between the brain and other parts of the body. Finally, the CNS and PNS refer to the specific subsets of the nervous system that perform distinct functions in the body.
