What acts as communication wires for the central nervous system?

The communication wires for the central nervous system are primarily composed of neurons, which transmit electrical signals. These signals travel through axons, long projections of neurons, that are often insulated by myelin sheaths to enhance speed and efficiency. Additionally, synapses facilitate communication between neurons, allowing for the transfer of information via neurotransmitters. Together, these structures enable rapid and coordinated communication throughout the brain and spinal cord.
