Explanation
Tetanus is an infection of the nervous system caused by Clostridium tetani bacteria.

The other options (respiratory system, circulatory system, bones, and muscles) are incorrect because they are not the primary systems affected by tetanus infection.

About Neurons and Nerve Impulse
Neurons receive and transmit information through dendrites, the cell body and axons. The topic explains resting potential, depolarization, repolarization, refractory periods and saltatory conduction, followed by synaptic transmission through neurotransmitters. An action potential is distinct from the graded potential produced at a receptor.
