Giant axons
WebThe giant axons appear as three large profiles (gf) near the dorsal surface of the cord, seen better in the close-up figure. The median giant axon in the center is larger (and conducts more rapidly) than the two lateral giants … WebBut...even the largest axons without myelin in the animal kingdom, such as the 1 mm diameter squid giant axon, only has a conduction velocity of 20-25 m/s second! You have myelinated axons in your body (the A alpha fibers) that are only 13-20 μm in diameter (1/100 of the size of the squid axon), yet have conduction velocities that are 80-120 m/s!
