What carries impulses from the skin to the central nervous system?
A pseudo-unipolar neuron referred to as an afferent neuron carries a sensory impulse to the spinal cord, which is part of the central nervous system.
A pseudo-unipolar neuron has one axon which comes from the cell body (soma) and then splits into two branches, the peripheral axonal branch which carries the impulse from the skin, and the central axonal branch which carries the impulse to the spinal cord; it has no dendrites, which distinguishes it from a bipolar neuron.
The impulse moves along the peripheral branch and then to the central branch, skipping the soma.

When a stimulus is continuous but you no longer respond to it the process is called?
Sensory adaptation (also called neural adaptation) is the process by which the nervous system 'adapts' to a continuous stimulus. Sensory (nervous) impulses are sent at gradually decreasing rates until we no longer feel the stimulus, although it is still there. This is why we sometimes forget that our glasses are on our foreheads or that we still have a pencil tucked behind our ear. The only sense that does NOT undergo sensory adaptation is obviously pain, because pain is so critical for survival that ignoring it can lead to serious injury or death.
