When a neuron receives a stimulus that is very strong?
all or none fashion
Do negative feedback mechanisms decrease or end the original stimulus?
tough question. negative feedback system is a dynamic system, therefore always in change. so it can end the stimulus if needed, but usually decreases the stimulus to maintain balance. Balance is the key word in the negative feedback system
An organism reacts to a stimulus with an?
An organism reacts to a stimulus with a response.
What is the definition of a submaximal stimulus?
Submaximal Stimulus results in complete contraction of some fibers. It causes contraction more than subminimal stimulus and less than maximal stimulus.
The process of changing physical stimulus to neural stimulus is called what?
Transduction is the process of changing physical stimulus to natural stimulus. This causes receptor cells to produce an electrical change in response.
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
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.
What is the smallest increase or increase in the intensity of a stimulus a person can detect?
just noticeable difference
Many people chew to gum to increase saliva formation when their mouth is dry. what is this type of stimulus?
mechanical 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?
When a strong conditioned stimulus is paired with a neutral stimulus, the neutral stimulus can acquire the ability to elicit the conditioned response even without the presence of the original conditioned stimulus. This process is known as second-order conditioning, where the neutral stimulus becomes a conditioned stimulus through association with the strong conditioned stimulus.
Do graded potentials increase amplitude as they move away from the stimulus?
No, they actually decrease in amplitude as they move away from the stimulus point.
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.
When a neuron receives a stimulus that is very strong?
all or none fashion
What is an exceptionally strong stimulus that can trigger a response?
Relative refractory period
Is conducting stimulus strong enough to generate a nerve impulse?
It depends on the strength of the stimulus. A threshold voltage has to be reached before the nerve can be stimulated.
