  2. Cardiac plexus - Wikipedia

    en.wikipedia.org/wiki/Cardiac_plexus

    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. The sympathetic component of the cardiac plexus comes from cardiac nerves, which originate from the

  3. Ganglionated plexi - Wikipedia

    en.wikipedia.org/wiki/Ganglionated_plexi

    Ganglionated plexi (GP) comprise the intrinsic cardiac autonomic nervous system composed of autonomic ganglia of the heart atrium and ventricles. [1] Cholinergic neurons throughout the GPs project to all areas of the heart, [2] The GP are embedded in the epicardial fat pads, consisting of only a few neurons or as many as 400 neurons. [1]

  4. Parasympathetic nervous system - Wikipedia

    en.wikipedia.org/wiki/Parasympathetic_nervous_system

    These cardiac branches go on to form cardiac and pulmonary plexuses around the heart and lungs. As the main vagus nerves continue into the thorax they become intimately linked with the esophagus and sympathetic nerves from the sympathetic trunks to form the esophageal plexus.

  5. Superior cardiac nerve - Wikipedia

    en.wikipedia.org/wiki/Superior_cardiac_nerve

    The superior cardiac nerve arises by two or more branches from the superior cervical ganglion, and occasionally receives a filament from the trunk between the first and second cervical ganglia. It runs down the neck behind the common carotid artery , and in front of the Longus colli muscle ; and crosses in front of the inferior thyroid artery ...

  6. Cardiac branches of the vagus nerve - Wikipedia

    en.wikipedia.org/wiki/Cardiac_branches_of_the...

    The cervical cardiac branches (sometimes ambiguously called superior cardiac branches) of vagus nerve, two or three in number, arise from the vagus, at the upper and lower parts of the neck. The upper branches are small, and communicate with the cardiac branches of the sympathetic. They can be traced to the deep part of the cardiac plexus.

  7. Splanchnic nerves - Wikipedia

    en.wikipedia.org/wiki/Splanchnic_nerves

    Renal plexus: Lumbar splanchnic nerves: L1–2: Inferior mesenteric ganglia, ganglia of intermesenteric and hypogastric plexuses: Sacral splanchnic nerves: sacral part of sympathetic trunk: inferior hypogastric plexus and ganglia to the pelvic viscera: Pelvic splanchnic nerves: parasympathetic: S2–S4

  8. Cardiac nerve - Wikipedia

    en.wikipedia.org/wiki/Cardiac_nerve

    The cardiac nerves are autonomic nerves which supply the heart. [1] They include: Superior cardiac nerve [1] (nervus cardiacus cervicalis superior)

  9. Cardiopulmonary nerves - Wikipedia

    en.wikipedia.org/wiki/Cardiopulmonary_nerves

    Cardiopulmonary nerves are splanchnic nerves that are postsynaptic and sympathetic. [1] They originate in cervical and upper thoracic ganglia [1] and innervate the thoracic cavity.
