Consider the following tibial nerve conduction velocity (NCV) test results below. A unique feature of distal limb motor neurons is that the axons taper abruptly in the lower extremities. What is the best explanation for why these average NCVs are decreasing with increasing height? Height (in) Mean NCV (m/s) < 5’3” 51 5’3” – 5’7” 49 > 5’7” 47
