	~~==Anatomy==~~		The '''cardiac plexus''' is a complex network of nerves located at the base of the heart. It plays a crucial role in the autonomic regulation of the heart, influencing both the heart rate and the force of cardiac contractions. The cardiac plexus is part of the [[autonomic nervous system]], which controls involuntary bodily functions.

	The cardiac plexus is situated in the [[mediastinum]], the central compartment of the thoracic cavity. It is formed by the cardiac branches of the [[vagus nerve]] and the [[sympathetic trunk]], and is divided into the superficial and deep cardiac plexus.		== Anatomy ==

	The ~~'''superficial~~ cardiac plexus~~'''~~ is ~~located beneath~~ the [[~~aortic arch~~]], ~~while the '''deep cardiac plexus''' is found between~~ the aortic arch and the [[~~trachea~~]].		The cardiac plexus is situated in the [[thoracic cavity]], specifically around the [[aortic arch]] and the [[tracheal bifurcation]]. It is divided into two main parts:

	~~==Function==~~		* The superficial cardiac plexus
			* The deep cardiac plexus

	The cardiac plexus is part of the [[autonomic nervous system]], which controls involuntary bodily functions. It carries both sympathetic and parasympathetic fibers, which regulate the heart's function.		=== Superficial Cardiac Plexus ===

	The [[~~sympathetic nervous system~~]] ~~increases heart rate~~ and ~~contractility, while~~ the [[~~parasympathetic nervous system~~]] ~~slows heart rate~~ and ~~reduces contractility. The balance between these two systems determines~~ the ~~heart's overall function~~.		The superficial cardiac plexus is located beneath the [[aortic arch]] and in front of the right [[pulmonary artery]]. It receives fibers from the [[left superior cervical sympathetic ganglion]] and the [[left vagus nerve]].

	~~Damage to the~~ cardiac plexus ~~can lead to serious heart conditions, such as~~ [[~~arrhythmia~~]] and [[~~heart failure~~]]. It ~~can also cause~~ [[~~neurocardiogenic syncope~~]]~~, a condition where~~ the ~~heart rate slows~~ and ~~blood pressure drops~~, ~~leading to fainting~~.		The deep cardiac plexus is found between the [[aortic arch]] and the [[tracheal bifurcation]]. It receives contributions from both the [[sympathetic]] and [[parasympathetic nervous system\|parasympathetic]] nervous systems. The sympathetic fibers originate from the cervical and upper thoracic ganglia, while the parasympathetic fibers come from the [[vagus nerve]].

	[[Cardiac surgery]] and other procedures that involve the heart or surrounding structures can potentially injure the cardiac plexus. Therefore, understanding the anatomy and function of the cardiac plexus is crucial for medical professionals.		== Function ==

	==~~See Also~~==		The cardiac plexus is responsible for the autonomic innervation of the heart. It modulates the heart's activity by:

			* Increasing heart rate and force of contraction through sympathetic stimulation
			* Decreasing heart rate through parasympathetic stimulation

			The balance between these two influences allows the heart to respond appropriately to the body's needs, such as during exercise or rest.

			== Clinical Significance ==

			Disorders of the cardiac plexus can lead to various cardiac conditions. For example, excessive sympathetic stimulation can result in [[tachycardia]], while excessive parasympathetic activity can cause [[bradycardia]]. Understanding the cardiac plexus is essential for diagnosing and treating autonomic dysfunctions of the heart.

'''Cardiac Plexus'''

The '''cardiac plexus''' is a complex network of [[nerve]] fibers located in the [[chest]], near the [[heart]]. It plays a crucial role in the autonomic regulation of heart function, including heart rate and rhythm.

==Anatomy==

The cardiac plexus is situated in the [[mediastinum]], the central compartment of the thoracic cavity. It is formed by the cardiac branches of the [[vagus nerve]] and the [[sympathetic trunk]], and is divided into the superficial and deep cardiac plexus.

The '''superficial cardiac plexus''' is located beneath the [[aortic arch]], while the '''deep cardiac plexus''' is found between the aortic arch and the [[trachea]].

==Function==

The cardiac plexus is part of the [[autonomic nervous system]], which controls involuntary bodily functions. It carries both sympathetic and parasympathetic fibers, which regulate the heart's function.

The [[sympathetic nervous system]] increases heart rate and contractility, while the [[parasympathetic nervous system]] slows heart rate and reduces contractility. The balance between these two systems determines the heart's overall function.

==Clinical Significance==

Damage to the cardiac plexus can lead to serious heart conditions, such as [[arrhythmia]] and [[heart failure]]. It can also cause [[neurocardiogenic syncope]], a condition where the heart rate slows and blood pressure drops, leading to fainting.

[[Cardiac surgery]] and other procedures that involve the heart or surrounding structures can potentially injure the cardiac plexus. Therefore, understanding the anatomy and function of the cardiac plexus is crucial for medical professionals.
