Chemoreceptor Trigger Zone - an overview ScienceDirect Topics

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. The CTZ is located within the area postrema, which is on the floor of the fourth … See more The CTZ is in the medulla oblongata, which is phylogenetically the oldest part of the central nervous system. Early lifeforms developed a brainstem, or inner brain, and nothing more. This part of the brain is responsible for … See more This integrates the emetic response. This is the area in which "a final decision is made" about whether to evoke an emetic response. This decision is based heavily on the information which the CTZ relays to the rest of the vomiting center, but also the chemoreceptors in the See more Antiemetic medications often target the CTZ to completely inhibit or greatly reduce vomiting. Most of these work by not allowing certain blood-borne drugs (usually pain killers or stimulants) to bind to their respective receptors located in the CTZ. The … See more Since the CTZ is located in the area postrema, a sensory circumventricular organ, it does not have a blood–brain barrier. This means that large polar molecules, such as … See more The vomiting center of the brain refers to the groups of loosely organized neurons in the medulla that include the CTZ within the area postrema and the nucleus tractus solitarii. One of the ways the chemoreceptor trigger zone implements its effects on the … See more Damage to the CTZ can come via stroke, physical injury, or over-excitation resulting in neuron death. Once the damage has occurred, the effects can cause the emetic response to … See more Oftentimes, doctors will "pre-treat" patients who might exhibit emetic responses due to drugs they prescribe them. Usually pain relieving drugs such as opioids are co-prescribed with anti … 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. The CTZ is located within the area postrema, which is on the floor of the fourth ventricle and is outside of the blood–brain barrier. It is also part of the vomiting center itself. The neurotransmitters implicated in the control of nausea and vomiting include acetylcholine, dopamine, iowa river hospice house marshalltown
