Neco 2018 Biology Question 26
Practice objective / multiple choice question 26 from the 2018 Neco Biology examination.
A person touches a hot object. The distance from the fingertip to the spinal cord is \(0.5\) m and from the spinal cord to the brain is \(0.8\) m. The afferent nerve conduction speed is \(80\) m/s. The synaptic delay at the spinal cord is \(0.5\) ms and at the brain is \(1\) ms. Muscle contraction time is \(30\) ms. The total measured reaction time is \(85\) ms. Assuming the efferent pathway runs from the brain to the muscle over a distance of \(0.6\) m, calculate the conduction speed of the efferent nerve fibers (in m/s).
