Practice objective / multiple choice question 4 from the 2020 Gce Model Questions Vol1 Biology examination.
A motor neurone that innervates a skeletal muscle fibre has an axon length of \(0.8\) m and a conduction velocity of \(60\) m·s⁻¹. The synaptic delay at the neuromuscular junction is \(0.5\) ms and excitation‑contraction coupling adds an additional \(2\) ms. Calculate the total time from the initiation of the action potential at the neurone soma to the onset of muscle contraction. Express your answer in milliseconds to one decimal place.
