What else can I help you with?
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.
Urination reflex is mediated by this part of the CNS?
The urination reflex is primarily mediated by the sacral region of the spinal cord, specifically the S2 to S4 segments. This area contains the neural pathways that control the bladder's contraction and the relaxation of the external urethral sphincter. Additionally, higher brain centers, such as the pontine micturition center, play a role in coordinating and regulating the urination process.

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 is complex act. CNS coordination is required for vomiting. The vomiting reflex is co-ordinate d in the vomiting center found in the medulla Oblangata which is a part of the CNS present at the base of the brain. The stimulus of vomiting like Dopamine, Serotonin are produced in different organs of the body. The vomiting center receives information from various parts of the body through stimulus and get stimulated.

Is the pupillary light reflex sympathetic?
While pupillary size in principle is controlled both by the sympathetic and the parasympathic nervous system, the typical closure of the pupil after illumination (i.e. the pupillary light reflex) is mediated by the parasympathetic innervation of the constrictor muscle of the pupil.
