The Vagus Nerve: An Overview

The vagus nerve, also known as the tenth cranial nerve, is a vital component of the human nervous system. It plays a crucial role in connecting the brain to various organs and systems throughout the body. Functioning as a major part of the parasympathetic nervous system, the vagus nerve helps regulate essential bodily functions, including heart rate, digestion, breathing, and even emotional responses.

Vagus Nerve Functions

The vagus nerve serves numerous functions that are vital for maintaining optimal bodily functions. These include:

  • Regulating heart rate and blood pressure
  • Controlling digestive functions, such as stomach acid production, digestive motility, and nutrient absorption
  • Influencing speech and voice control
  • Promoting relaxation and reducing stress
  • Assisting with the release of feel-good hormones like serotonin and oxytocin
  • Regulating inflammation and immune responses
  • Supporting the gut-brain connection

Vagus Nerve Dysfunction: Causes and Symptoms

  • Physical trauma or injury
