You’re walking down the street mindlessly. Suddenly, you remember that you had been planning on stopping by the grocery store on your way home.
Your mind had been occupied, and you don’t remember until the last second that you had to decide to turn. Well, you did turn, but something had to have prompted you to.
That’s the job of this nerve, one of the most important nerves in the body. It’s responsible for more bodily functions than you probably knew.
Let’s dive into what does the vagus nerve control.
What Is a Vagus Nerve?
The vagus nerve is the longest cranial nerve in the body. It extends from the brainstem down to the abdomen.
This nerve is responsible for many functions including heart rate, digestion, and immune response. This nerve is also involved in the control of the vocal cords and the production of speech.
What Does the Vagus Nerve Control?
The vagus nerve function by transmitting and receiving signals to regulate the operation of the digestive system, heart, lungs, and certain glands as it travels from the brainstem to the organs of the chest and belly. The cranium’s longest nerve has numerous branches that affect numerous organs.
This nerve serves as a conduit for sensory receptors carrying important data from the organs and ear to the brain. As a component of the autonomic nervous system, the brain’s nerve impulses regulate muscle contractions in the heart, lungs, and digestive system. Given that it is the tenth of the 12 pairs of cranial nerves, this nerve is also known as cranial nerve X.
The Importance of the Vagus Nerve?
The vagus nerve regulates several digestive processes. It is initially triggered by the food’s aroma, appearance, and flavor when it enters the mouth. This starts the digestive juices and stomach acids flowing.
Various nerve branches have an impact on swallowing, while others regulate peristalsis, the contraction of the muscles that carry food through the digestive system. The nerve branches that travel to the kidneys and intestines have an impact on how wastes are excreted.
This nerve affects blood pressure and heart rate. Its parasympathetic nervous system effects include a reduction in blood pressure and heart rate. The tightening of the smooth muscles by this nerve causes the bronchi in the lungs to constrict.
Hoarseness and other voice abnormalities can result from damage to a nerve branch that controls the muscles that move the vocal folds inside the larynx.
Why Do We Need to Stimulate the Vagus Nerve?
When the body is under stress, the vagus nerve signals the body to release stress hormones such as adrenaline and cortisol. These hormones prepare the body for action and help the individual to deal with the stressor.
However, chronic stress can lead to chronic activation of this nerve, which can eventually lead to health problems. In some cases, stimulating this nerve helps epileptic patients to regulate their seizures.
Doing vagus nerve stimulation at home is necessary. There is a vagus nerve guide that can help you stimulate this nerve.
Understanding Your Vagus Nerve
The vagus nerve is an extremely important part of the human body, controlling many vital functions. It is interesting to note that this nerve is also responsible for controlling the immune system. This means that this nerve plays a crucial role in maintaining health and preventing disease.
The nerve is also responsible for controlling the digestive system and heart rate. What does the vagus nerve control that’s so important to keeping the body healthy and functioning properly?
