Gce Model Questions Vol1 2019 Biology Question 15
Practice objective / multiple choice question 15 from the 2019 Gce Model Questions Vol1 Biology examination.
In a simple spinal reflex, the sensory receptor is located 0.5 m from the spinal cord, and the motor effector is 0.6 m beyond the spinal cord. The afferent (sensory) neuron conducts impulses at 50 m s\(^{-1}\) and the efferent (motor) neuron at 60 m s\(^{-1}\). (a) Calculate the total neural transmission time from receptor to effector, ignoring synaptic delay. (b) If the synaptic delay at the integration centre is 0.5 ms, what is the total response time of the reflex?
