Gce Model Questions Vol1 2017 Biology Question 24
Practice objective / multiple choice question 24 from the 2017 Gce Model Questions Vol1 Biology examination.
A stretch reflex involves an afferent sensory neuron of length \(0.8\ \text{m}\) conducting impulses at \(80\ \text{m·s}^{-1}\), and an efferent motor neuron of length \(0.6\ \text{m}\) conducting at \(60\ \text{m·s}^{-1}\). The synaptic delay at the spinal cord is \(0.5\ \text{ms}\) and the muscle contraction delay is \(5\ \text{ms}\). Calculate the total reaction time of the reflex in milliseconds.
