The vagus nerve, also known as the pneumiatric nerve, is a nerve that runs from the brain to the abdomen, but is wide from its origin to several branches that inert various cervical, chest and abdominal organs, with sensory and motor functions, being important for maintaining vital functions such as regulating heart rate and blood pressure, for example.
The pair of wavy nerves, located on each side of the body, is the tenth pair of a total of 12 cranial pairs that connect the brain to the body. As cranial pairs are called with Roman numerals, the vagus nerve corresponds to the X pair and is considered the widest of the cranial pairs.
- Some stimuli to vague nervousness.

- Changes in temperature simply by staying still for a long time.

- Because the person may have intense withdrawal.

- In the cortex of the heart and blood pressure.
The vagus nerve is the largest cranial pair and comes from the back of the spinal bulb, a structure of the brain that connects the brain to the spinal cord and the brain is sold through an opening of light, descending through the body and the chest must end up in the stomach.
During the wavy nerve tract, it inerts the pharynx, larynx, heart and other organs, and it is through it that the brain detects how it meets these organs and regulates their functions.
Some of the main functions of the vagus nerve include
In addition, the vagus nerve shares some of its functions with the glosopharyngeal nerve (par IX), especially in the area of the skin, being responsible for the taste sensation, where the vagus nerve is more related to the taste of sour and gloopharyngeal. taste with bitterness. .
Vagus nerve paralysis can cause difficulty swallowing and speaking, snoring, contractions of the pharynx and larynx muscles, changes in blood pressure and heart barking, this paralysis can be caused by trauma, injuries during surgeries, compression by tumors or certain neurological syndromes.
In addition, there are situations that cause excessive stimulation of the vagus nerve, generating a situation called vasovagal syndrome or abstinence, which is present in young people and is due to decreased heart rate and blood pressure, due to lack of oxygen in the brain. causing abstinence.
Vagal syncope can be caused by
The stimulus of vague nervousness could also occur through massages in the lateral region of the cell. Sometimes your doctor performs the vagal maneuver urgently to normalize a cardiac arrhythmia. You know more about what to do in case of abstinence.
