It would have the same pathway for the most part. There are times or "life or death" situations where a decision will be made in the spinal column but almost always it goes all the way to the brain. Specifically this pathway goes into the Thalamus of the brain and is there sent into the area of the brain (sensory or motor) to then be translated.
The correct answer for: Is it true that a signal from the nervous system that is sent from the brain to the hand would follow a different pathway than a signal sent from the hand to the brain. Is: This is false.
Explanation:
To understand this question we need to analyze the context. First of all, the brain sends a message through the nervous system terminals until it reaches the organ involved, in this case, tendons, muscles to be moved. Now, this is only possible because of the connection of millions of neurons. These neurons groups that have one objective are known as neuron families. So there is only one high way for the sign to travel from one way and the other. Nevertheless, if trauma and I mean physiological damage in neuron families happens, neuroplasticity and neurogenesis could find a way to create another link, but it is very difficult. Nevertheless, life always finds its ways.
