The sensory fibers'origin include the pharynx, middle ear, posterior one-third of the tongue ( including taste buds ); and the carotid body and sinus.

The carotid body detects changes in the composition of arterial blood flowing through it, mainly the partial pressure of oxygen, but also of carbon dioxide.
13.
Nonchromaffin paraganglia include carotid bodies and aortic bodies, some are distributed in the ear, along the vagus nerve, in the larynx and at various other places.
14.
They are generally present at the head and neck, most often at carotid body or jugulo-tympanic, they rarely secrete hormones and commonly have a familial history.

Baroreceptors are stretch receptors located in the aortic sinus, carotid bodies, the venae cavae, and other locations, including pulmonary vessels and the right side of the heart itself.

Similarly, baroreceptors are stretch receptors located in the aortic sinus, carotid bodies, the venae cavae, and other locations, including pulmonary vessels and the right side of the heart itself.
17.
In humans, hypoxia is detected by the peripheral chemoreceptors in the carotid body and aortic body, with the carotid body chemoreceptors being the major mediators of reflex responses to hypoxia.

In humans, hypoxia is detected by the peripheral chemoreceptors in the carotid body and aortic body, with the carotid body chemoreceptors being the major mediators of reflex responses to hypoxia.
19.
These responses might be activated by dopamine released from the carotid body under conditions of low oxygen, but whether arterial dopamine receptors perform other biologically useful functions is not known.
20.
This ability to ignore a response to CO 2 is likely brought on by increase carotid bodies which are sensor for oxygen levels which let the animal know its available oxygen supply.
