vagus nerves

The 10th of the 12 pairs of cranial nerves that arise directly from the brain. The vagus nerves arise from the sides of the MEDULLA OBLONGATA and pass down the neck to supply and control the throat, LARYNX, BRONCHI, lungs,OESOPHAGUS and heart. They then enter the abdomen on the front and back of the oesophagus and supply the stomach and the intestines as far as the descending COLON. The vagus is an important part of the AUTONOMIC NERVOUS SYSTEM. From the Latin vagus , wandering or straying.

vagus nerves

the tenth pair of cranial nerves, originating from the brain stem and descending through the neck, thorax and abdomen, giving off branches with both afferent and efferent components to many organs and tissues. The efferent fibres are mainly part of the parasympathetic nervous system, including those that slow the heart and those that innervate smooth muscle and glands in the respiratory and gastrointestinal tracts. The main afferent fibres are visceral afferents from thoracic and abdominal organs.
