Detailed explanation-1: -Although the nervous system is very complex, there are only two main types of cells in nerve tissue. 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.
Detailed explanation-2: -A neuron, neurone, or nerve cell is an electrically excitable cell that fires electric signals called action potentials.
Detailed explanation-3: -Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances. Glia are also essential to nervous system function, but they work mostly by supporting the neurons.
Detailed explanation-4: -The correct answer is c) All neurons have the same four functional zones.
