Igcse Model Questions Vol1 2023 Biology Question 33
Practice objective / multiple choice question 33 from the 2023 Igcse Model Questions Vol1 Biology examination.
Nerve impulse speed in axons depends on their diameter and whether they are myelinated. For myelinated axons the speed is proportional to the square of the diameter, while for unmyelinated axons it is directly proportional to the diameter. Given that a myelinated axon of diameter 20 µm conducts impulses at 120 m/s, estimate the speed of a myelinated axon with a diameter of 10 µm.
