Growth cone: This is the specialized end of the growing axon that generates the motive force for elongation.
Neurotrophins: This originates from the Greek word trophikos which means ‘nourish’. These neurotrophins provide factors which keep the neuron alive and for growth. These factors are usually growth factors.
Netrins: A family of diffusible molecules that act as attractive or repulsive cues to guide growing axons.
