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).
How does the cerebral cortex overrides the reflex?
The cerebral cortex can not over ride reflexes. Reflex are mediated at the level of the spinal cord.
Is nausea a autonomic reflex?
Yes. You are right. Most probably nausea is mediated through autonomic nervous system.
Does the vagus nerve control vomiting?
Yes, the vagus nerve plays a role in controlling the process of vomiting. It sends signals to the brain to trigger the reflex response of vomiting when necessary.
Is the pupillary light reflex sympathetic?
No, the pupillary light reflex is mediated by the autonomic nervous system, specifically the parasympathetic nervous system. When light is detected by the retina, it triggers a reflex that causes the pupils to constrict, a response mediated by the parasympathetic nervous system.

Is vomiting reflex coordinated by the medulla?
yes
Can you disable your vomit reflex?
No. Drugs that treat nausea and vomiting will diminish this reflex, though.
What agent causes no gag reflex and decreased eye movement and nausea and vomiting?
Botulism causes no gag reflex and decreased eye movement and nausea and vomiting.
Is the corneal reflex a cord-mediated reflex?
The corneal reflex may be elicited by lightly touching the cornea with a wisp of cotton; this sensory stimulus is transmitted by the first branch of the trigeminal nerve to the brainstem. There, thanks to connections of the trigeminal nerve with the facial (motor) nerve, a motor response occurs leading to contraction of the orbicularis oculi. The result is blinking or closing the eye on the same side. Thus this reflex is a brainstem and not a cord-mediated reflex.
Is nausea a autonomic reflex?
Yes. You are right. Most probably nausea is mediated through autonomic nervous system.
Why does the body vomit?
Vomiting is a natural reflex triggered by the ingestion of toxins. This reflex is an important one to ensure that recognized toxins are expelled from the body.
Does the vagus nerve control vomiting?
Yes, the vagus nerve plays a role in controlling the process of vomiting. It sends signals to the brain to trigger the reflex response of vomiting when necessary.
What internal stimulus causes vomiting?
Vomiting can be triggered by various internal stimuli, such as infections, food poisoning, motion sickness, migraine headaches, and certain medications. These stimuli can activate the vomiting center in the brainstem, leading to the reflex of vomiting.
Is the pupillary light reflex sympathetic?
No, the pupillary light reflex is mediated by the autonomic nervous system, specifically the parasympathetic nervous system. When light is detected by the retina, it triggers a reflex that causes the pupils to constrict, a response mediated by the parasympathetic nervous system.
Is a heartbeat a reflex?
No, a heartbeat is not a reflex. It is a coordinated and involuntary contraction of the heart muscle controlled by the heart's own electrical system, known as the cardiac conduction system. Reflexes are typically involuntary responses to stimuli mediated by the nervous system.
