Trace the flow of information through the nervous system from a stimulus, to receptor, coordinator, effector, and final response.
Explain the structure and physiological function of a reflex arc, emphasizing its role in automatic and rapid responses without conscious brain involvement.
Describe the function of a synapse in transmitting chemical impulses across the gap between two connecting neurones.
Detail specific experimental methods used to measure human reaction times and recall that typical values range from 0.3 to 0.9 seconds.
Plan and systematically carry out an investigation to determine the effect of a specific factor on human reaction times.
