The characteristic movement of cells from the dorsal ridge of the neural tube to a variety of locations in a vertebrate embryo.

The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.

The collection of axons into a bundle of rods, known as a fascicle.

The process whose specific outcome is the progression of the mesoderm over time, from its formation to the mature structure. The mesoderm is the middle germ layer that develops into muscle, bone, cartilage, blood and connective tissue.

The regrowth of axons following their loss or damage at the neuromuscular junction. Motor axons regenerate after injury and they form neuro-muscular junctions with skeletal myofibers similar to normal ones.

The process whose specific outcome is the progression of the optic nerve over time, from its formation to the mature structure. The sensory optic nerve originates from the bipolar cells of the retina and conducts visual information to the brainstem. The optic nerve exits the back of the eye in the orbit, enters the optic canal, and enters the central nervous system at the optic chiasm (crossing) where the nerve fibers become the optic tract just prior to entering the hindbrain.

Any process that stops, prevents, or reduces the frequency, rate or extent of axon outgrowth.

Any process that activates or increases the frequency, rate or extent of synaptic growth at neuromuscular junction.

Any process that activates, maintains or increases the rate of axon regeneration.
