The only cardiac nerves which do not enter into the formation of the deep part of the cardiac plexus are the superior cardiac nerve of the left sympathetic trunk, and the lower of the two superior cervical cardiac branches from the left vagus nerve, which pass to the superficial part of the plexus.
Autonomic plexuses can contain both sympathetic and parasympathetic neurons. The cardiac plexus is located near the aortic arch and the carina of the trachea. The pulmonary plexus supplies innervation to the bronchial tree. The celiac, or solar plexus, is located around the celiac trunk and contains the celiac ganglia. The solar plexus is the ...
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]
The sympathetic trunk is a fundamental part of the sympathetic nervous system, and part of the autonomic nervous system.It allows nerve fibres to travel to spinal nerves that are superior and inferior to the one in which they originated.

Ganglia provide relay points and intermediary connections between different neurological structures in the body, such as the peripheral and central nervous systems. Among vertebrates there are three major groups of ganglia: Dorsal root ganglia (also known as the spinal ganglia) contain the cell bodies of sensory (afferent) neurons.
The nerves go down to the root of the neck with these following association: Posterior: "prevertebral fascia overlying anterolateral surface of vertebral bodies" Superior: "common carotid artery" Inferior: "subclavian artery" Laterally: "sympathetic trunk" [2]
Each recurrent laryngeal nerve supplies the larynx, the heart, the trachea and the esophagus. Another set of nerves that come off the vagus nerves approximately at the level of entering the thorax are the cardiac branches of the vagus nerve. These cardiac branches go on to form cardiac and pulmonary plexuses around the heart and lungs. As the ...
