Answer:
What Are the Parts of the Nervous System?
The nervous system is made up of the central nervous system and the peripheral nervous system:
The brain and the spinal cord are the central nervous system.
The nerves that go through the whole body make up the peripheral nervous system.
The human brain is incredibly compact, weighing just 3 pounds. It has many folds and grooves, though. These give it the added surface area needed for storing the body's important information.
The spinal cord is a long bundle of nerve tissue about 18 inches long and 1/2-inch thick. It extends from the lower part of the brain down through spine. Along the way, nerves branch out to the entire body.
