Stress related?: The vomiting reflex is controlled by two units in the brain medulla--one receives nerve impulses from the GI tract, the other is a chemical receptor. Both have nerve connections to not only the GI tract (pharynx, mesenteric vessels, bile ducts) but also from brain corticobulbar areas that mediate smells, sights, ; taste. Vomiting apparatus responds to a variety of GI ; brain inputs like stress.
