Question

Discuss one specific receptor type of the general senses; give location, type, and function

Answer 1

Chemoreceptors are sensores that detect changes in CO2 O2 and the pH or detect the levels of carbon dioxide in the blood by monitoring the concentrations of hydrogen ions in the blood.

  

The central chemoreceptors are located in the respiratory center at the base of the brain, monitor the levels of carbon dioxide and oxygen by detecting changes in the pH levels of the cerebral spinal fluid.

The peripheral chemoreceptors are located in the carotid (carotid sinus) and aortic bodies (aortic arch). The carotid bodies respond to arterial hypoxia by increasing the firing rate from the carotid sinus nerve.
