How Do Supplies Travel Along a Long Axon?
Axonal microtubules provide tracks for ATP-powered cargo transport. Kinesin-family motors commonly support outward transport, while cytoplasmic dynein supports return toward the cell body. Moving cargo is distinct from propagating an electrical signal.

What the illustration shows
Navy-and-gold educational poster showing a neuron with cell body left and terminal right. An enlarged axon contains two parallel microtubules, minus ends left and plus ends right. A purple kinesin example carries gold cargo right; red dynein carries blue cargo left. A lower inset shows a motor and ATP. Text distinguishes cargo movement from electrical signaling. Gold AllHumanBody.com and full slogan appear below.
How to interpret this poster
- Generic mammalian axon example, not a statement that all kinesins move outward or each cargo has only one motor. Routes are regulated.
- Motor shapes, cargo contents, track number and spacing are schematic, not a measured speed, atomic structure or complete traffic map.
- No absence of local protein synthesis, disease diagnosis or treatment is inferred. Glow is illustrative.
- AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
- Fine annotations need enlargement; the full description provides an accessible text alternative.
- Display the full uncropped illustration; do not trim titles, legends or boundary annotations.
