Where do impulses travel?
Nerve impulses travel up through nerves, into the spinal cord and into one of the different lobes of the brain depending on where the impulse comes from. For example, if the impulse comes from your ear, the impulse would travel to the temporal lobe.

What would a substance that decreases membrane premeability to sodium increase or decrease the probability of generating a nerve impulse?
Allowing more sodium ions into a nerve generates a nerve impulse. so decreasing membrane permeability of sodium would decrease the probability of generating a nerve impulse.
What would happen if the anterior ramus of the spinal nerve is damaged or transected?
The end organ or muscle innervated by that particular spinal nerve component would atrophy.
What would be the result of damage to ventral root of a spinal nerve?
Would lead to loss of both sensory & motor function. Ventral ramus is the anterior division of a spinal nerve.
Would there be a loss of sensory or motor function when someone damages the dorsal root of a spinal nerve?
Yes this can happen when any nerve is damaged but this is a greater danger if its an actual Spinal Nerve.
What is a nerve massage called?
I think you might mean Message,and that would be an "impulse".
What is Gates theory of pain?
The Gate Control Theory of Pain, proposed by Ronald Melzack and Patrick Wall in 1965, suggests that the experience of pain is influenced by both sensory and psychological factors. According to this theory, sensory information is processed through a "gate" in the spinal cord, which can be opened or closed by factors such as attention, emotions, and beliefs. By understanding and manipulating these factors, it may be possible to modulate the perception of pain.
What would happen if the brain and spinal cord didn't have nerve cells?
death
What If the dorsal root of a spinal nerve is severed?
Sensory input would be blocked.
An efferent nerve takes an impulse towards the brain?
The nerve that takes the impulses to the brain would be vagus.
Would a substance that decreases membrane permeability to sodium increase or decrease the generating of a nerve impulse?
Decrease
