Neco 2019 Biology Question 2
Practice objective / multiple choice question 2 from the 2019 Neco Biology examination.
In a stretch reflex, the afferent sensory neuron conducts at 80\,m/s, the efferent motor neuron at 60\,m/s, the synaptic delay is 0.5\,ms and the muscle contraction delay is 5\,ms. The total observed latency from stretch to contraction is 30\,ms. Assuming the afferent and efferent pathways are of equal length, what is the total length of the neural pathway (afferent plus efferent) in metres?
