The basic parts of the nervous system are the brain, the spinal cord and the nerves.
Explanation:
The brain and the spinal cord form the Central Nervous System, which is the place that receives the stimuli from the exterior and other parts of the body. In the Central Nervous System, the information travels through the spinal cord up to the brain where the information is processed, and an answer is given. This answer travels through the spinal cord and then though the peripherical nerves up to its specific destination.
