Vagal tone is activity of the vagus nerve, the 10th cranial nerve and a fundamental component of the parasympathetic branch of the autonomic nervous system. This branch of the nervous system is not under conscious control and is largely responsible for the regulation of several body compartments at rest. Vagal activity results in various effects, including: heart rate reduction, vasodilation/constriction of vessels, glandular activity in the heart, lungs, and digestive tract, liver, i… birdhouse businessWebb20 feb. 2024 · The sympathetic nervous system (SNS) and the parasympathetic nervous system (PSNS) are both components of the autonomic nervous system (ANS).
