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.
The vagus nerve (/ ˈ v eɪ. ɡ ə s /), also known as the tenth cranial nerve, cranial nerve X, or simply CN X, is a cranial nerve that carries sensory and motor fibers. It creates a pathway that interfaces with the parasympathetic control of the heart, lungs, and digestive tract.
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.
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 ...
The esophageal plexus (oesophageal plexus in British-English) is formed by nerve fibers from two sources, branches of the vagus nerve, [1] [2] and visceral branches of the sympathetic trunk. [3] [4] The esophageal plexus and the cardiac plexus contain the same types of fibers and are both considered thoracic autonomic plexus.
the vagus nerve, part of the parasympathetic branch of the autonomic nervous system, to lower heart rate. The cardiovascular centre also increases the stroke volume of the heart (that is, the amount of blood it pumps). These two changes help to regulate the cardiac output, so that a sufficient amount of blood reaches tissues.
The two branches of the autonomic nervous system work together to increase or slow the heart rate. The vagus nerve acts on the sinoatrial node, slowing its conduction and modulating vagal tone, via the neurotransmitter acetylcholine and downstream changes to ionic currents and calcium of heart cells.
