The vomiting reflex is mediated by the?
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)
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.
What is an fact about the medulla oblongata?
It has the mechanisms for controlling our body's reflex activities such as coughing and vomiting
What is receptor mediated exocytosis of glucose?
What is receptor mediated exocytos
The vomiting reflex is mediated by the?
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)
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 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.
Does vomit clean your body?
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 before they enter the bloodstream and circulate to peripheral organs where they may incur greater damage. In this sense, vomiting is an important mechanism not to "cleanse" the body, but to ensure it doesn't "get dirty". In addition to the natural vomiting reflex, we can initiate vomiting in other circumstances. Individuals with eating disorders, for example, may induce vomiting to stay thin. In this sense, vomiting is not at all protective. In fact, if vomiting is induced frequently for a sustained amount of time, it can severely damage the individual.
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 eating potassium cause vomiting?
Consumption of a large dose of potassium ions, such as potassium chloride, induces a vomiting reflex to expel most of the potassium before it can be absorbed
If when a student touches a hot stove and withdraws his hand and then yells why does the yelling occur after his hand is withdrawn?
The withdrawal of the limb is mediated by a spinal reflex pathway mediated by the larger A fibres while the sensation of pain is carried to the brain much slower by the c-fibres.
If you try to gag how is vomiting optional?
It really isn't at that point. If you are tyring to make yourself gag, it probably will end in vomiting as it is a natural and un-controlled reflex to gag and then vomit.
