Igcse Model Questions Vol1 2024 Biology Question 27
Practice objective / multiple choice question 27 from the 2024 Igcse Model Questions Vol1 Biology examination.
In a simple reflex, the distance from the skin receptor to the spinal cord is 0.8 m and the nerve conduction velocity is 50 m·s\(^{-1}\). The synaptic delay at the spinal cord is 0.5 ms. The distance from the spinal cord to the effector muscle is 0.4 m with a conduction velocity of 60 m·s\(^{-1}\). (a) Calculate the total neural transmission time for the reflex in milliseconds. (b) If the measured reaction time is 30 ms, how much additional time is accounted for by central processing?
