4 unusual facts about Sympathetic nervous system


Effective arterial blood volume

The kidney mechanisms used to restore EABV include, (1) sympathetic nerve activity; (2) Atriopeptin (ANP) secretion from the atria; (3) Starling forces; (4) Renin-angiotensin-aldosterone system.

Emotional self-regulation

It has been shown to effectively reduce facial expressivity, subjective feelings of positive emotion, heart rate, and sympathetic activation.

Expressive Suppression

Expressive suppression has physiological influences such as decreasing heart rate, increasing blood pressure, and increasing sympathetic activation (Dan-Glauser & Gross, 2011).

Hunting reaction

This is probably caused by a sudden decrease in the release of neurotransmitters from the sympathetic nerves to the muscular coat of the arteriovenous anastomoses due to local cold.
