The neuron is the structural and functional unit of the nervous system. These are specialized excitable cells of the body capable of transmitting for conducting excitation along their membrane. They also receive stimuli and transfer them from one to another neuron. A typical neuron consists of a cell body and processes as a dendrite and axon that terminate into knob or button. Dendrites carry impulses towards the cyton and the action is specialized as fibers that conduct the impulse away from cyton. So take the Neurons quiz and know more about neurons.
