Gce Model Questions Vol1 2018 Biology Question 40
Practice objective / multiple choice question 40 from the 2018 Gce Model Questions Vol1 Biology examination.
A reflex arc consists of a sensory neuron 0.8 m long conducting at 60 m s⁻¹, a motor neuron 1.2 m long conducting at 80 m s⁻¹, and a synaptic delay of 0.5 ms at the spinal cord. A voluntary response uses a cortical pathway of 2.5 m conducting at 70 m s⁻¹ and a synaptic delay of 2 ms. Calculate the total time from stimulus to muscle contraction for both the reflex and the voluntary response, and state which is faster and by how many milliseconds.
