||P.559 left column 2nd paragraph:"A variety of cells transport organelles through their cytoplasm (Schliwa, 1984). This phenomenon is thought to be the basis of fast axonal transport in neurons (Smith, 1980 Tsukita and Ishikawa, 1980) where organelles are transported great distances, over one meter in some animals, between the cell body and the nerve terminal (Grafstein and Forman, 1980). Fast axonal transport is directed towards, as well as away from, the nerve cell body at rates of up to 5 µm/sec in mammals (primary source)."
