Question

Nerve Growth Factor (NGF) is crucial for the survival and maintenance of sympathetic and sensory neurons. When a target cell releases NGF, it signals to the axon that it has been "accepted," promoting the survival and growth of the axon in that specific location. NGF does not directly dictate axon pathfinding to specific target cells, regulate axonal elongation in response to body growth, or stimulate the formation of new neurons in neuron-deficient brain areas.
