Vagotonia
Vagotonia
Vagotonia (pronounced: vay-go-toh-nee-uh) is a medical term that refers to the dominance or overactivity of the parasympathetic nervous system (PNS) over the sympathetic nervous system (SNS). This condition is often associated with various symptoms such as bradycardia, hypotension, and gastrointestinal hypermotility.
Etymology
The term "Vagotonia" is derived from the Latin word "vagus", meaning "wandering", and the Greek word "tonos", meaning "tension" or "tone". The term is used to describe the state of increased tone, or tension, in the vagus nerve.
Symptoms
Vagotonia can present with a variety of symptoms, including:
- Bradycardia: Abnormally slow heart action.
- Hypotension: Abnormally low blood pressure.
- Gastrointestinal hypermotility: Increased movement in the gastrointestinal tract, which can lead to symptoms such as diarrhea and abdominal cramping.
Related Terms
- Parasympathetic nervous system: The part of the involuntary nervous system that serves to slow the heart rate, increase intestinal and glandular activity, and relax the sphincter muscles.
- Sympathetic nervous system: The part of the nervous system that serves to accelerate the heart rate, constrict blood vessels, and raise blood pressure.
- Vagus nerve: The tenth cranial nerve that interfaces with the parasympathetic control of the heart, lungs, and digestive tract.
