Neco 2019 Biology Question 18
Practice objective / multiple choice question 18 from the 2019 Neco Biology examination.
A student touches a hot wire and the measured reaction time from stimulus to muscle contraction is \(0.250\)\,s. The sensory neuron conducts impulses from the receptor to the spinal cord at \(50\)\,m\,s^{-1} over a distance of \(0.80\)\,m. The motor neuron conducts impulses from the spinal cord to the effector muscle at \(40\)\,m\,s^{-1} over a distance of \(0.60\)\,m. Assuming a single synapse in the spinal cord, calculate the synaptic delay (in milliseconds) at the spinal cord.
