Neco 2022 Biology Question 20
Practice objective / multiple choice question 20 from the 2022 Neco Biology examination.
A motor neuron that innervates a skeletal muscle fibre has a myelinated axon \(0.8\ \text{m}\) long. The conduction velocity in myelinated fibres is \(80\ \text{m}\,\text{s}^{-1}\). After the impulse reaches the terminal, a synaptic delay of \(0.5\ \text{ms}\) occurs before the muscle fibre contracts. Calculate the total time from the initiation of the action potential at the neuron's soma to the onset of muscle contraction, expressed in milliseconds.
