Answer:
Fibers called nerves carry important messages back and forth between your body and your brain. That network -- your nervous system -- has two parts: Your brain and spinal cord make up your central nervous system. The nerves in the rest of your body make up your peripheral nervous system
Step-by-step explanation:
Messages, in the form of electrical impulses, constantly travel back and forth between the brain and other parts of the body. A special cell called a neuron is responsible for carrying these messages. There are about 100 billion neurons in the human brain. A neuron has three main parts.
The thalamus carries messages from the sensory organs like the eyes, ears, nose, and fingers to the cortex.
