(n. ) (Graece ὁ ἄξων, áxon quod Latine axis sonat) est pars cellularum nervalium, inter perikaryon (soma) et synapses interposita. Axon est, ut dentrita, protrusio cytoplasmatis cellulae nervalis, quae signa transmittit. Longitudines eius inter cellulas corporis nervales diversae sunt: Corticis cerebralis interneuronis axones breves sunt, ac neuronis tractus pyramidalis longissimi.

 Procreatio et axonum crescentia 
Generatio axonum momentum maximum procreatione systematis nervosi ineunte habet. Elongatio eius conu crescente, proteinis actini onerato ita microfilamenta formantibus, fit. Auxilio factoribus neurotrophicis biochemico directio crescentium axonum, atque tempus gubernantur.
