Neco Model Questions Vol1 2018 Biology Question 40
Practice objective / multiple choice question 40 from the 2018 Neco Model Questions Vol1 Biology examination.
An action potential originates in a sensory neuron whose axon is 0.9 m long and is myelinated, conducting at 70 m s\(^{-1}\). It reaches a synapse where a delay of 0.6 ms occurs before the signal is transmitted to an interneuron. The interneuron's unmyelinated axon is 1.2 m long and conducts at 30 m s\(^{-1}\), followed by a second synaptic delay of 0.8 ms before activation of a motor neuron (ignore the motor neuron's conduction time). Calculate the total time, in milliseconds, from the initial stimulus to activation of the motor neuron, rounded to one decimal place.
