Table 1.

Experimentally determined transport ranges and known/hypothesized transport types (adapted from Brown (Brown, 2000)).

Transport Type	Velocity (mm/day)	Velocity (μm/s)	Example Cargo Type(s)
Fast
--Anterograde	200–400	2.31–4.63	Golgi-derived vesicles, tubules, neurotransmitters
--Retrograde	200–400	2.31–4.63	enodosomes, lysosomes
--Bidirectional	50–100	0.58–1.16	mitochondria
Slow
--Component A	0.3–3	0.003–0.035	neurofilaments
--Component B	2–8	0.02–0.08	microfilaments, actin
