The sympathetic nervous system, which helps your heart and other vital organs function all the time, increases activity in response to danger or stress, preparing the body for extra demands. Stress is ...

The sympathetic nervous system (SNS) plays a crucial role in the regulation of cardiovascular function, mediating rapid adjustments in heart rate and arterial blood pressure during stress, physical ...

The sympathetic nervous system was thought to have evolved with jawed vertebrates. But lampreys—jawless, parasitic fish that suck out the blood of their hosts—have a simple one, per recent research.

The sympathetic nervous system (SNS) is integral to the regulation of blood pressure, orchestrating rapid adjustments in vascular tone and heart rate to maintain homeostasis. By modulating peripheral ...

The portion of our nervous systems responsible for the 'fight or flight' response can shape the severity of potentially deadly C. difficile infections, according to new research. The portion of our ...

With terrifyingly sharp teeth arranged around a circular mouth, lampreys look about as primitive a vertebrate as you could imagine. But a new study finds that the animals have a surprising similarity ...

During this period of cultural chaos, the most important thing we can do for ourselves and each other is to avoid the autonomic nervous system's freeze response. Source: Lisa Langhammer/used with ...

The term “sympathetic nervous system overload” sounds daunting, but the root cause is pedestrian: stress. Stress is, of course, something we all experience all the time, but left unchecked, it can ...

The portion of our nervous systems responsible for the "fight or flight" response can shape the severity of potentially deadly C. difficile infections, new research from the University of Virginia ...
