The Sympathetic Efferent Fibers of the Vagus Nerve are supposed to arise in the dorsal nucleus (nucleus ala cinerea). These preganglionic fibers are all supposed to end in sympathetic ganglia situated in or near the organs supplied by the vagus sympathetics.... The trunk ends in the superior cervical ganglion at about the level of the second cervical nerve. From this uppermost sympathetic ganglion, post-ganglionic sympathetic fibers follow the internal carotid artery into the skull, contributing to a carotid plexus on the artery's surface.

The innervation of the heart refers to the network of nerves that are responsible for the functioning of the heart. The heart is innervated by sympathetic and parasympathetic fibres from the autonomic branch of the peripheral nervous system. The network of nerves supplying the heart receives contributions from the right and left vagus nerves, as well as contributions from the sympathetic trunk how to set up lighting for no shadows Sympathetic Trunk. The sympathetic chain is a paired bundle of nerve fibers that runs from the base of the skull to the coccyx, just lateral to the vertebral bodies.

How To Tell The Sympathetic Trunk From Vagus Nerve
The anatomy of the vagus nerve has been shown to be variable among species. 10, 11 In human, the vagus nerve is anatomically separated from the sympathetic trunk. 10, 12 In contrast, the vagus nerves are intermingled and interconnected with sympathetic fibers in some animals.

- The sympathetic chain descends in front of the neck of the 1st rib, head of 2nd-10th ribs and along the bodies of T11 and T12 vertebrae, in front of posterior intercostal nerve and vessels, enters behind the medial arcuate ligament to become continuous with the lumbar sympathetic trunk.
- The superior cervical sympathetic cardiac nerve originates on each side from the lower part of the superior cervical ganglion or from the sympathetic trunk below it, and runs downwards near the trunk behind the carotid sheath.
