Pioneer Axon

Pioneer axon is the classification given to axons that are the first grow in a particular region. They originate from pioneer neurons, and have the main function of laying down the initial growing path that subsequent growing axons, dubbed follower axons, from other neurons will eventually follow.

Several theories relating to the structure and function of pioneer axons are currently being explored. The first theory is that pioneer axons are specialized structures, and that they play a crucial role in guiding follower axons. The second is that pioneer axons are no different from follower axons, and that they play no role in guiding follower axons.

Anatomically, there are no differences between pioneer and follower axons, although there are morphological differences. The mechanisms of pioneer axons and their role in axon guidance is currently being explored. In addition, many studies are being conducted in model organisms, such grasshoppers, zebrafish, and fruit flies to study the effects of manipulations of pioneer axons on neuronal development.

    I am not belittling the brave pioneer men but the sunbonnet as well as the sombrero has helped to settle this glorious land of ours.
