Stimulus Transduction in the Carotid Body Chemoreceptor: A Brief Review of Recent Findings – Chris Peers (p.18)

The carotid bodies are small, paired organs located at the sinus nerve bifurcations of the common carotid arteries (see Fig IA). Each capillary is highly vascularised, an essential arrangement for these chemoreceptor organs as they are designed to detect changes in the levels of arterial oxygen, carbon dioxide and pH.
