Gce Model Questions Vol1 2021 Biology Question 8
Practice objective / multiple choice question 8 from the 2021 Gce Model Questions Vol1 Biology examination.
A simple stretch reflex involves a sensory neuron of length \(0.5\ \text{m}\) conducting at \(80\ \text{m s}^{-1}\), a motor neuron of length \(0.4\ \text{m}\) conducting at \(60\ \text{m s}^{-1}\), and a single synaptic delay of \(0.5\ \text{ms}\). Calculate the total time (in milliseconds) from the onset of muscle stretch to the resulting muscle contraction. Is this time less than the \(30\ \text{ms}\) required for effective postural stability? Give the total time and answer Yes or No.
