How Does Your Nervous System Work?

The nervous system in your body is made up of two parts: the central nervous system and the peripheral nervous system.

Right now, it’s taking care of millions of details to keep you alive.

The brain and the spinal cord make up the central nervous system. The spinal cord transmits sensory messages to the brain and motor messages from the brain. Sensory nerves carry messages from receptors to the brain. If you touch a hot iron, pain receptors tell your brain to move your hand. Motor nerves send signals from the brain to the muscles in the body. These nerves help us to do things such as walk, kick a ball or pick up an object.

The peripheral nervous system transports the messages between the central nervous system and the body. It consists of cranial and spinal nerves that carry messages to and from every cell in your body.

Part of the peripheral nervous system is called the autonomic nervous system. The actions of the autonomic nervous system are generally involuntary. It controls actions such as breathing, your heartbeat and digestion ~ actions you don’t even have to think about!

The autonomic nervous system is made up of the sympathetic system that alerts the body when there is an emergency or danger. When this happens, your heart beats faster, your blood pressure rises, and your pupils dilate in what is called a “flight or fight” response. The parasympathetic system returns your body to normal once the danger has passed.

Chiropractic care is designed to improve the integrity of the nervous system so that everything works the way it should. That is why it is important to have your spine checked at regular intervals.


Dr. Marisa Asks some important questions of interest to Shoreline residents - Chiropractor Shoreline Dr. Marisa Asks...

Will chiropractic adjustments make my spine too loose?
No. Only the spinal joints that are fixated and "locked up" receive attention. The occasional spinal joint that moves too much is passed over so weakened muscles and ligaments can strengthen and heal.
Is a muscle spasm a cause or an effect?
With the knee-jerk use of muscle relaxers, you'd think it was a cause. But it's an effect. Chiropractors know that bones don't move unless muscles move them. And muscles don't contract unless commanded by the nervous system. That's why your nervous system is the focus of our Shoreline chiropractic practice.
