When a neuron receives a stimulus that is very strong?
When a neuron receives a very strong stimulus, it may reach its threshold potential and fire an action potential. This can lead to the release of neurotransmitters, sending a signal to other neurons. The strength of the stimulus can affect the frequency of action potentials generated by the neuron.
The primary chemical stimulus used to control breathing is changes in the concentration of?
The primary chemical stimulus used to control breathing is changes in the concentration of carbon dioxide in the blood. When carbon dioxide levels increase, it triggers an increase in breathing rate to remove excess carbon dioxide and restore balance.
Identify and describe how an organism could respond to an external stimulus and describe a response to an internal stimulus?
An example of an external stimulus is a painful prick (and any other stimulus that happens OUT side the organism ). The organism could respond by pulling away from the pain caused by the stimuli. An example of an internal stimulus is the feeling of hunger or thirst (or any other stimulus that happens IN side the organism). The organism could respond by eating or drinking. a behavior
What taste stimulus triggers the strongest response in your taste buds?
The taste stimulus that triggers the strongest response in taste buds varies among individuals, but generally, sweet and salty tastes tend to elicit strong responses due to their pleasurable and satisfying qualities.
Do negative feedback mechanisms decrease or end the original stimulus?
Negative feedback mechanisms work to decrease or counteract the original stimulus, rather than completely ending it. The goal is to bring the system back to its set point or normal level by regulating the stimulus within a certain range.
The strong stimulus can increase the?
Number of times the neuron fires
Strong stimuli cause the amplitude of action potentials generated to increase?
Yes. ....Up to a point. There is a threshold the stimulus must surpass before creating a CAP (compound action potential). Anything below this threshold is called subthreshold. Once the stimulus is strong enough cause a CAP it is a stimulus threshold. At this point the CAP will continue to increase as the intensity of the stimulus increases (now termed suprathreshold) until a maximal stimulus causes a maximum response. Any stimulus stronger than the maximal stimulus is called a supramaximal and does not result in any larger a CAP than the maximum response caused by the maximal stimulus. source: http://www.unmc.edu/physiology/Mann/mann12.html
Do graded potentials increase amplitude as they move away from the stimulus?
No, graded potentials do not increase in amplitude as they move away from the stimulus. The amplitude of graded potentials will decrease with distance from the stimulus site due to the loss of charge.
Does strong stimuli cause the strength of action potentials to increase?
No, it doesn't become "larger" - the peak potential is always the same - it is a digital signal. Stronger stimulus will cause the nerve cell to fire more often - therefore stimulus strength is translated as action potential frequency.
Many people chew to gum to increase saliva formation when their mouth is dry. what is this type of stimulus?
mechanical stimulus
Will graded potential increase amplitude as they move away from the stimulus point?
No, graded potentials do not increase in amplitude as they move away from the stimulus point. They dissipate as they travel along the neuron membrane due to leak channels and distance from the original stimulus.
What is the strongest stimulus to increase respiratory rate and depth is to increase the blood concentration of?
Carbon dioxide
When a strong conditioned stimulus is paired with a neutral to become a second conditioned stimulus?
This isn't really a whole question but I'm guessing you're referring to classical conditioning. A good example of this is Pavlov's expeirment with dogs. He looked at how much they salivated when presented with food (the conditioned stimulus) and then paired the food with a ringing bell (neutral stimulus) and eventually the dogs started salivating at the sound of the bell even if there was no food.
Are the people of Ohio going to receive a stimulus check?
No one will receive a stimulus check. You will only a notice an increase in pay. The average wage earner will see a $13 a week increase.
What is an exceptionally strong stimulus that can trigger a response?
Relative refractory period
What is the difference between stimulus frequency and stimulus strength?
<P> <P>The stimulus frequency is how often the stimulus is admitted. For example, every 30 seconds, every minute and 1/2, etc. <P>Stimulus strength describes the level of force used to administer the stimulus such as mild, moderate or maximum.</P>
Does a large stimulus produce a higher amplitude in a action poteintial?
No, the amplitude of an action potential is constant and does not vary with the strength of the stimulus. Instead, the frequency of action potentials fired by a neuron can increase with a stronger stimulus.
