Understanding the Nervous System
The central nervous system is made up of the brain and the spinal cord. These two are attached at the hole on the base of the skull, and the spinal cord’s length reaches the lower back. The nerves that are found in different body parts comprise the peripheral nervous system.
The brain is where thought is processed into signals, the signals travel through the nervous system and reaches the rest of the body, and these body parts respond to the signal by moving or producing certain chemicals. Our five senses receive signals from the environment and the brain processes these signals into various kinds of taste, smell, colors or figures, temperature or pressure, and sound.
