Detailed explanation-1: -A type of cell that receives and sends messages from the body to the brain and back to the body. The messages are sent by a weak electrical current. Also called neuron.
Detailed explanation-2: -The central nervous system (which includes the brain and spinal cord) is made up of two basic types of cells: Neurons, the nerve cells that send and receive signals. Glia, cells that provide structure in the brain.
Detailed explanation-3: -The actual nerve cell is the neuron. It is the “conducting” cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell. The word “neuroglia” means “nerve glue.” These cells are nonconductive and provide a support system for the neurons.
