As pressure and extend lower, the rate of baroreceptor firing decreases, as well as cardiac facilities improve sympathetic stimulation and reduce parasympathetic stimulation.

The vagus nerve is a protracted, wandering nerve that emerges from the brainstem and gives parasympathetic stimulation to numerous organs within the thorax and abdomen, such as the heart.[34] The nerves within the sympathetic trunk arise through the T1-T4 thoracic ganglia and journey to both equally the sinoatrial and atrioventricular nodes, as well as for the atria and ventricles.
