What are the central Chemoreceptors normally most sensitive to?
Regarding this, what are the peripheral chemoreceptors normally most sensitive to?
The peripheral chemoreceptors are directly sensitive to the partial pressures of arterial oxygen and carbon dioxide as well as Blood pH; however, the mechanisms by which the concentrations of these molecules is connected to chemoreceptor activity is not well-understood.
Likewise, which chemical is most likely to directly affect central Chemoreceptors? Central chemoreceptors in the pons (locus ceruleus) and medulla (raphe nuclei, ventrolateral nuclei, and nucleus of tractus solitarius) are influenced primarily by changes in carbon dioxide tension (Pco2) concentrations.
Also, what do Central chemoreceptors respond to?
central chemoreceptors: Located within the medulla, they are sensitive to the pH of their environment. peripheral chemoreceptors: The aoritic and carotid bodies, which act principally to detect variation of the oxygen concentration in the arterial blood, also monitor arterial carbon dioxide and pH.
Which situation causes central chemoreceptors to increase the respiratory rate?
Central respiratory chemoreception is the mechanism by which an increase in brain PCO2 stimulates breathing. The term also refers to the respiratory stimulation caused by metabolic acidosis (blood acidification at normal levels of CO2).
