The cardiac plexus is a plexus of nerves situated at the base of the heart that innervates the heart. The cardiac plexus is divided into a superficial part, which lies in the concavity of the aortic arch, and a deep part, between the aortic arch and the trachea. The two parts are, however, closely connected.

2022年10月25日 · The network of nerves supplying the heart is called the cardiac plexus. It receives contributions from the right and left vagus nerves, as well as contributions from the sympathetic trunk. These are responsible for influencing heart rate, cardiac output, and contraction forces of the heart.

The cardiac plexus provides both sympathetic and parasympathetic innervation to the heart. Both types of nerve fibers wind along the cardiac tissue and arteries, passing primarily to atrial regions, specifically around the sinuatrial node.

2025年1月22日 · The cardiac plexus is a network of autonomic nerves that innervates the heart, regulating its functions through both sympathetic and parasympathetic fibers. It is composed of nerve fibers from the vagus nerve (parasympathetic) and sympathetic trunk (sympathetic), as well as contributions from the cardiac branches of the thoracic sympathetic ...

2023年4月8日 · The cardiac plexus is a network of autonomic nerves and ganglia situated at the base of the heart. It is formed by cardiac branches derived from both the sympathetic and parasympathetic nervous systems. Gross anatomy. Parasympathetic cardiac nerves reach the heart from the vagus nerve (cranial nerve X) via

Cardiac plexus refers to a meshwork of neurons and ganglia which are responsible for innervating the cardiac tissue. It comprises of two sub-parts: superficial and deep.

2022年4月17日 · The deep cardiac plexus lies in front of the tracheal bifurcation behind the aortic arch and is formed by cardiac nerves arising from the cervical ganglia of the sympathetic trunk and cardiac branches off the vagus and recurrent laryngeal nerves.

The superficial cardiac plexus provides both sympathetic and parasympathetic innervation to the heart. Both types of nerve fibers pass from the plexus into the cardiac tissue by following the coronary arteries and their branches.

The cardiac plexus refers to a large network of nerves located around the base of the heart, formed by cardiac sympathetic nerves and the cardiac branches of the vagus nerve. It distributes these nerves and their branches to the myocardium and vessels leaving the heart.

2019年8月8日 · The cardiac plexus is divided into the superficial and deep parts. The superficial part lies beneath the arch of the aorta, in front of the right pulmonary artery. It consists of cardiac branches from the left sympathetic trunk and the left vagus nerve.
