Vomiting center is located at

(A) Area postrema # Chemoreceptor cells in the medulla initiate vomiting when they are stimulated by certain circulating chemical agents.> Chemoreceptor trigger zone cells are located in Area postrema, a V-shaped band of tissue on the lateral walls of the fourth ventricle near the apex.> Swallowing, coughing, sneezing, gagging, and vomiting are also reflex responses integrated in the medulla oblongata.> Vomiting is another example of the way visceral reflexes integrated in the medulla include coordinated and carefully timed somatic as well as visceral components.> Vomiting centre in the reticular formation of the medulla really consists of various scattered groups of neurons in this region that control the different components of the vomiting act.
