What node does the vagus nerve innervate?
The right vagus nerve primarily innervates the SA node, whereas the left vagus innervates the AV node; however, there can be significant overlap in the anatomical distribution. Atrial muscle is also innervated by vagal efferents, whereas the ventricular myocardium is only sparsely innervated by vagal efferents.
What Plexuses are innervated by the vagus nerve?
The vagus contributes to the: Cardiac, pulmonary and oesophageal plexuses. Stomach and liver (via the anterior vagus) Small and large intestine as far as the splenic flexure (travelling via the superior mesenteric artery).

Where is the vagus nerve and what does it do?
The vagus nerve is located on both the left and right sides of the body and runs from the brainstem through the neck into the chest and abdomen. One of the longest of all the cranial nerves, the vagus nerve serves several important functions. It regulates the heartbeat, breathing and sweating.
What is the effect of the vagus nerve on the heart?
