Respiratory stimulus refers to the physiological signals that trigger the process of breathing, primarily driven by the body's need to regulate oxygen and carbon dioxide levels. Key factors include rising levels of carbon dioxide in the blood, decreased oxygen levels, and changes in blood pH, all of which are detected by chemoreceptors. These signals prompt the respiratory center in the brain to adjust the rate and depth of breathing accordingly, ensuring that gas exchange meets the body's metabolic demands.

Carbon dioxide is the most important stimulus to breathe.
The corticol motor will activate stimulating the pontine centers to modify VRG breathing rhythm. The VRG will make adjustments to the stimulus going to the respiratory centers
pCO2 is the strongest respiratory stimulus because it directly affects the acidity of the blood. Increased levels of carbon dioxide (CO2) lead to a rise in hydrogen ion concentration, resulting in lower pH (respiratory acidosis). Chemoreceptors in the brainstem and peripheral arteries are highly sensitive to these changes in pCO2, triggering an increase in respiratory rate and depth to eliminate excess CO2 and restore normal pH levels. This regulation is crucial for maintaining homeostasis and ensuring adequate oxygen supply to tissues.
The hypoxic drive, or the body's response to low oxygen levels, is a secondary stimulus to breathe in most individuals. It becomes the primary drive in patients with certain chronic respiratory diseases, such as COPD, where there is a blunted response to high carbon dioxide levels. This shift can lead to decreased respiratory drive with supplemental oxygen therapy, so caution is needed in prescription to prevent respiratory depression.
'Stimulus' is the correct spelling.
The difference between an external stimulus and an internal stimulus is that an external stimulus is a stimulus that comes from outside an organism. But an internal stumulus is a stimulus that comes from inside an organism. An example for an external stimulus can be that when you are cold, you put on a jacket. An example for an internal stimulus is that when you feel hungry, you eat food.
The characteristics are modality (type of stimulus), intensity (strength of stimulus), duration (length of stimulus), and location (where the stimulus occurred).
Generalization is the tendency to respond to a stimulus that is similar but not identical to a conditioned stimulus.
A neutral stimulus becomes a conditioned stimulus through a process called classical conditioning. This happens when the neutral stimulus is paired consistently with an unconditioned stimulus that naturally elicits a response. Over time, the neutral stimulus begins to evoke the same response as the unconditioned stimulus, becoming a conditioned stimulus.
A neutral stimulus is a stimulus that initially does not elicit a specific response. In classical conditioning, the neutral stimulus becomes associated with a meaningful stimulus through repeated pairing, eventually causing the neutral stimulus to elicit the same response as the meaningful stimulus.
