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.

The area postrema was first named and located in the gross anatomy of the brain by Magnus Gustaf Retzius, a Swedish anatomist, anthropologist and professor of histology. In 1896, he published a two-volume monograph on the gross anatomy of the human brain in which the area postrema was mentioned. In 1975, evidence of neurons in the area postrema of several mammal species was published. WebThe AP along with the nucleus of the solitary tract (NTS) and the dorsal motor nucleus of the vagus makes up the so-called dorsal vagal complex, which is the major termination site of vagal afferent nerve fibers.
