part_of part of part of axonogenesis biological_process De novo generation of a long process of a neuron, including the terminal branched region. Refers to the morphogenesis or creation of shape or form of the developing axon, which carries efferent (outgoing) action potentials from the cell body towards target cells. axon morphogenesis axon growth GO:0007409 neuron long process generation Note that 'axonogenesis' differs from 'axon development' in that the latter also covers other processes, such as axon regeneration (regrowth after loss or damage, not necessarily of the whole axon).
