Gce Model Questions Vol1 2022 Biology Question 49
Practice objective / multiple choice question 49 from the 2022 Gce Model Questions Vol1 Biology examination.
In a laboratory experiment a student measures the reaction time to a tap on the patellar tendon. The distance from the sensory receptor at the tendon to the spinal cord (L2) is \(0.4\ \text{m}\) and the distance from the spinal cord to the quadriceps muscle is \(0.5\ \text{m}\). The recorded total reaction time is \(0.12\ \text{s}\). It is known that central processing requires \(0.03\ \text{s}\) and the synaptic delay at the neuromuscular junction is \(1\ \text{ms}\). Assuming the afferent and efferent nerve fibres have the same conduction velocity, calculate this average conduction velocity in \(\text{m s}^{-1}\) (rounded to one decimal place).
