Cardiac plexus

The cardiac plexus (here: cardiac plexus ) in a representation of the right border cord and its connections

The cardiac plexus ( latin for "heart braid") is a braid of nerve fibers at the base of the heart outside of the pericardium to the autonomic control of the heart. It contains several nerve cell nodes ( ganglia cardiaca ), the largest of which, the Wrisberg ganglion, is located in the cavity of the aortic arch near the ligamentum arteriosum .

construction

Basically, the cardiac plexus can be divided into two parts, which are functionally closely linked: a superficial part ( pars superficialis , also plexus cardiacus superficalis ) and a more pronounced, deep part ( pars profunda , also plexus cardiacus profundus ). The branches from the deep part serve to control the heart. This lies behind the aortic arch and to the side of the bifurcation of the trachea and contains fibers from the cardiac nerves on both sides. The superficial part, on the other hand, lies below the aortic arch in front of the right pulmonary artery and mainly contains fibers from the left cardiac nerves.

The cardiac plexus primarily follows the coronary arteries . It continues on the aortic arch as the thoracic aortic plexus ; it is also connected to the pulmonary plexus on both sides .

The cardiac plexus receives sympathetic fibers from the second to fourth thoracic segment of the spinal cord (Th2-Th4) via the superior cardiacus cervicalis from the superior cervical ganglion , the median cardiacus cervicalis from the medium cervical ganglion and the inferior cardiacus cervicalis from the ganglion stellatum . In addition, it receives parasympathetic fibers from the vagus nerve ( Rami cardiaci ). Pain-conducting fibers and fibers from the chemo- ( glomera aortica ) and pressoreceptors also run in the nerve tract .
