Abstract

Carotid body (CB) chemoreceptors sense arterial PO2 and PCO2/pH becoming activated in hypoxic hypoxia and in all types of acidosis. The sensing structures in the CB are chemoreceptor cells (CBCC), which are connected synaptically with the sensory nerve endings of the carotid sinus nerve (CSN). In situations of hypoxia and acidosis, CBCC are activated and their rate of release of neurotransmitters (NT) increase, promoting an increase in the activity of the CSN and subsequent ventilatory and cardiovascular reflexes (5).
