    The textbook states :
    " When an electrical impulse reaches the end of a neurone, neurotransmitters are secreted directly onto cells so nervous response is localised "
    What does nervous response localised mean in this particular topic?

    Maybe it means that the action of the neurotransmitters is limited on the area where the neurone ends, because they will only act on the receptors of the tissue that are close to the neuronal end. Where as if you compare it with a hormone which is released in the blood, that has a 'systemic' effect rather that a localised effect because it acts on receptors of various tissues.

    Hope that makes sense
