The sympathetic nervous system
The parasympathetic nervous system, part of the autonomic nervous system, decreases pulse rate. It is sometimes referred to as the rest and digest system.
heart rate is controlled by hormones as well as the autonomous nervous system. adrenaline, a hormone increases heart rate while the sympathetic nervous system decreases heart rate. Medulla Oblongata
Stimulation of the vagus nerve decreases heart rate. The vagus nerve is an important part of the parasympathetic nervous system.
Chronotropy refers to the heart's ability to change its heart rate. Positive chronotropy increases heart rate, while negative chronotropy decreases heart rate. This is controlled by the autonomic nervous system and various hormones.
The parasympathetic nervous system helps regulate heart rate by slowing it down. It works in opposition to the sympathetic nervous system, which speeds up heart rate.
The cause and effect of heart rate in relation to the nervous system can be varied. When the heart rate is low, the nervous system is limited in terms of blood supply and this may cause seizures.
Heart muscles has there own rhythm of contraction. The sinoatrial node has the fastest rate of contraction. That is why it governs the rhythm of the heart. You have the control of the autonomic nervous system over the heart rate. Stimulation of the sympathetic nervous system increase the heart rate. Stimulation of the parasympathetic nervous system decrease the heart rate.
The nervous system controls heart and respiratory rates.
sympathetic nervous system
The subdivision of the peripheral nervous system (PNS) that regulates the activity of the heart is the autonomic nervous system (ANS). Specifically, the sympathetic division increases heart rate and contractility, while the parasympathetic division, primarily through the vagus nerve, decreases heart rate. Together, these divisions help maintain homeostasis in cardiac function.
The parasympathetic division of the autonomic nervous system is responsible for decreasing heart rate. It releases acetylcholine to slow down the heart's activity.
