Gce Model Questions Vol1 2023 Biology Question 26
Practice objective / multiple choice question 26 from the 2023 Gce Model Questions Vol1 Biology examination.
In a physiological experiment, a researcher measures the latency between a brief tap applied to the skin and the onset of contraction in the flexor carpi radialis muscle of the forearm. The recorded latency is \(45\ \text{ms}\). When the same tap is applied to the sole of the foot, the latency to contraction of the tibialis anterior is \(70\ \text{ms}\). Both measurements are taken at the same ambient temperature. Based on typical latency ranges for different reflex pathways, identify which type of reflex (monosynaptic stretch reflex, polysynaptic withdrawal reflex, or supraspinally mediated response) most likely mediates each response. Justify your answer.
