The Nervous System serves as the body control center and communications electrical-chemical wiring network.

The Nervous System is divided into two parts – the Central Nervous System and the Peripheral Nervous System. The Central Nervous System is divided into two parts also – the brain and the spinal cord. And the Peripheral Nervous System is divided into two parts – the Somatic Nervous System (consists of nerve fibers) and the Autonomic Nervous System (consists of the sympathetic nervous system, the parasympathetic nervous system, and the enteric nervous system).

Fun Facts:

- As we get older the brain loses almost one gram per year!
- The average human brain weighs 1.3 to 1.4 kg (approximately 3 pounds).
- The brain contains about 100 billion nerve cells.
- The vertebral column is about 70 cm long.

We learned about the Nervous System and the parts that make it function. The Nervous System is the body system that sends signals to the rest of the body to help us live our everyday lives. It is one of the most important body systems, without it we wouldn’t be able to do anything on our own!
