The chemoreceptor trigger zone is a bilateral set of centers in the brainstem lying under the floor of the fourth ventricle.CTZ has connection with vomiting center and play indirectly to stimulate vomiting.. Electrical stimulation of these centers does not induce vomiting, but application of emetic drugs does - if and only if the vomition centers are intact. The chemoreceptor trigger zones function as emetic chemoreceptors for the vomition centers - chemical abnormalities in the body (e.g. emetic drugs, uremia, hypoxia and diabetic ketoacidosis) are sensed by these centers, which then send excitatory signs to the vomition centers. Many of the antiemetic drugs act at the level of the chemoreceptor trigger zone.

No. The vomiting reflow is mediated by the chemoreceptor trigger zone (CTZ) in the medulla of the brainstem, which communicates with the vomiting center (to mediate the vomiting reflex)

Thes are the sites of action in the brain where antipsychotics work. The Basal ganglia, areas of the limbic system, the chemoreceptor trigger zone ,and the cerebral cortex
No, a chemoreceptor is a type of nociceptor.

Maxeron has three areas of activity. 1) Maxeron restores normal gastro-intestinal motility in patients with impaired functioning. 2) Maxeron prevents nausea and vomiting of local origin by decreasing the sensitivity of the visceral nerves involved 3) Maxeron prevents nausea and vomiting of central origin by decreasing the sensitivity of chemoreceptor trigger zone.
Good question! Since ipecac acts on a center in the brain called the chemoreceptor zone, once enough ipecac is present in the blood it will induce vomiting. The chemoreceptor zone is triggered by substances in the blood (such as poisons, alcohol, bacteria, viruses, etc.). So if enough ipecac is absorbed into the bloodstream through the rectal wall, the person will vomit The other zone in the brain that can cause vomiting is the vomit center, which causes vomiting by stimulation from the body's senses (like if we smell something gross, or if we get motion sickness, or if we gag ourselves).
