WebMay 24, 2024 · Vomiting or emesis is the result of two separate medulla oblongata zones: the chemoreceptor trigger zone (CTZ) and the integrative vomiting center. Messages arrive in the CTZ from the blood and cerebrospinal fluid when certain levels of toxins are present. These messages are forwarded to the integrative vomiting center. The CTZ has many different types of receptors, which are specific to different types of toxins or drugs that might be present in the bloodstream and thus that can affect the CTZ. Types of CTZ receptors include dopamine, serotonin, histamine, substance P, opioid, and acetylcholine receptors. See more The chemoreceptor trigger zone (CTZ) is an area of the medulla oblongata that receives inputs from blood-borne drugs or hormones, and communicates with other structures in the vomiting center to initiate vomiting. … See more Since the CTZ is located in the area postrema, a sensory circumventricular organ, it does not have a blood–brain barrier.
