Match the following components and processes of the human nervous system with their descriptions:

<p>Nerve impulse = An electrical signal that travels along nerve cells Reflex arc = A rapid and automatic integration and coordination of stimuli with the responses of effectors Stimulus = Something that triggers a nerve impulse Motor neurone = Carries the response to the appropriate effector</p> Signup and view all the answers
