Vagal escape occurs when the parasympathetic nervous system (vagus nerve) is temporarily overridden by the sympathetic nervous system. This can lead to an increase in heart rate and blood pressure, as well as other physiological responses like bronchodilation and pupil dilation. It is a protective mechanism that allows the body to respond to stress or threat.

Vagal escape occurs when heart is stimulated by what?
Vagal escape occurs when the parasympathetic nervous system, specifically the vagus nerve, fails to regulate the heart rate and the heart muscle is instead stimulated by other mechanisms. This can happen in situations where there is a prolonged increase in sympathetic nerve activity or when there is a dysfunction in the parasympathetic nervous system.
What nerve conveys parasympathetic signals to the heart?
Vagal
Does a gas escape through a tiny opening into a vacuum during effusion?
Yes, a gas can escape through a tiny opening into a vacuum during effusion. Effusion is the process by which gas molecules pass through a small opening into a vacuum due to their random motion. This happens because of the difference in pressure between the gas inside and the vacuum outside.
What is vagal nerve stimulation?
Vagal nerve stimulation is a medical procedure that involves delivering electrical impulses to the vagus nerve, which is a cranial nerve that plays a role in regulating many bodily functions. It is commonly used to treat conditions such as epilepsy and depression that have not responded to other treatments.

What causes vagal escape?
when cardiac muscle begins to contract after a brief period of rest after vagal stimulation its initial strength of contraction increases to a plateau by staircase effect strong vagal stimulation of heart can stop heart beat for few seconds

What happens to animals during Mt Vesuvius eruptions?
The same as the people. They escape or die.
What happens when you press the escape key during a slide show?
In PowerPoint, if you press the escape key during a slide show It will stop the slide show.
How can the heart overcome excessive vagal stimulation?
Excessive vagal stimulation can be overcome by engaging in activities that increase sympathetic tone, such as exercise or deep breathing. In severe cases, medications like atropine can be used to block the effects of excessive vagal stimulation on the heart.
What is the function of the vagal lobe?
to sense taste :-)
What happens if you see a black widow?
Nothing happens better you get escape from there
What nerve conveys parasympathetic signals to the heart?
Vagal
Which phase change occurs during evaporation?
The phase change that occurs during evaporation is when a liquid changes into a gas. This process happens when the molecules of the liquid gain enough energy to escape into the air.
Does the vagus nerve stimulator cause vagal inhibition?
Yes
Increased vagal stimulation would cause?
Increased vagal stimulation would cause a decrease in heart rate and blood pressure. The vagus nerve is part of the parasympathetic nervous system, which promotes relaxation and slows down physiological processes.
Why do you collapse after standing for long periods?
When you stand for a long time, it may cause your knees to buckle resulting in a vaso-vagal reaction. When this happens, there is a decrease in blood pressure which can make a person collapse or faint.
