Fast axonal transpo is a component of ohograde axonal transpo. What is the rate of fast axonal transpo?

Fast axonal transpo occur at a rate of 400mm/d. Fast and slow axonal transpo are components of ohograde transpo system. Ohograde transpo moves from the cell body to the axon. It occurs along microtubules that run along the length of the axon and requires two molecular motors, dynein and kinesin. Slow component of this transpo occur at a rate of 10 mm/d. Retrograde transpo, occur opposite direction, from the nerve ending to the cell body. It occurs along the microtubules at about 200 mm/day. Ref: Barrett K.E., Barman S.M., Boitano S., Brooks H.L.
