vomiting

n.
the reflex action of ejecting the contents of the stomach through the mouth. Vomiting is controlled by a special centre in the brain that may be stimulated by drugs (e.g. apomorphine) acting directly on it; or by impulses transmitted through nervous pathways either from the stomach (e.g. after ingesting irritating substances or in stomach diseases, such as peptic ulceration or pyloric stenosis), the intestine (e.g. in intestinal obstruction), or from the inner ear (in motion sickness). The stimulated vomiting centre sets off a chain of nerve impulses producing coordinated contractions of the diaphragm and abdominal muscles, relaxation of the muscle at the entrance to the stomach, etc., causing the stomach contents to be expelled.
