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.
What else can I help you with?
What part of the brainstem that receives information from the chemoreceptor trigger zone?
Medulla Oblangota
What is the site of action in the brain where antipsychotics work?
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
The vomiting reflex is mediated by the?
Vomiting reflex is mediated by the vomiting center in the brainstem, specifically the area postrema. This area receives input from various parts of the body, including the gastrointestinal tract and higher brain centers, to initiate the coordinated response of vomiting.
Vomiting reflex 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).
Where is the emetic center located?
The emetic center is located in the brainstem, specifically in the medulla oblongata. It is responsible for triggering the physiological response of vomiting when it receives signals from various sources such as the gastrointestinal tract, vestibular system, or chemoreceptor trigger zone in the brain.
What is a chemoreceptor?
sensing the oxygen
What is maxeron tablet for?
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.
If someone drinks ipecac will they vomit?
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).
What means chemoreceptor?
Chemoreceptores can detect chemical stimuli.
Excruciating facial pain upon stimulation of a trigger zone?
Bootje patrick...bootje
The trigger zone of a neuron includes?
The trigger zone of a neuron includes the axon hillock, where graded potentials are summed together to determine if an action potential will be initiated. It is the region where voltage-gated sodium channels are concentrated and play a crucial role in generating an action potential. If the depolarization at the trigger zone reaches a certain threshold, an action potential will be generated and propagated down the axon.
What would a chemoreceptor allow you to do?
detect smell
