After coursing along the stylopharyngeus muscle and providing its nerve supply, the nerve assumes a medial relation to the external carotid artery and anteromedial to the internal carotid artery. (medscape.com)
Chemoreceptor5
This signal may be in the form of an action potential, if the chemoreceptor is a neuron, or in the form of a neurotransmitter that can activate a nerve fiber if the chemoreceptor is a specialized cell, such as taste receptors, or an internal peripheral chemoreceptor, such as the carotid bodies. (wikipedia.org)
In physiology, a chemoreceptor detects changes in the normal environment, such as an increase in blood levels of carbon dioxide (hypercapnia) or a decrease in blood levels of oxygen (hypoxia), and transmits that information to the central nervous system which engages body responses to restore homeostasis. (wikipedia.org)
2005). Overexpression of the nNOS gene in the carotid body elevates nNOS protein expression and NO production in center failing animals on track amounts and reverses the improved chemoreceptor Daidzin novel inhibtior function in center failing (Li et al. (ap26113.com)
Artery2
Blood oxygen and carbon dioxide are in fact directly sensed by the carotid body , a small collection of chemosensors at the bifurcation of the carotid artery, innervated by the petrosal (IXth) ganglion. (wikidoc.org)
A terminal branch of the left or right common carotid artery which supplies oxygenated blood to to the throat, neck glands, tongue, face, mouth, ear, scalp and dura mater of the meninges[MP]. (virtualflybrain.org)
Chemoreflex3
The peripheral arterial chemoreflex, due to the carotid body generally in most species primarily, plays a significant role in the control of deep breathing and in autonomic control of cardiovascular function. (ap26113.com)
2007). As rabbits lack practical aortic chemoreceptors Inasmuch, the peripheral chemoreflex is due to the carotid bodies with this species primarily. (ap26113.com)
2005). Hence, a proclaimed downregulation of Daidzin novel inhibtior endogenous NOS in the carotid body seems to play a significant function in the improved peripheral Daidzin novel inhibtior chemoreflex in center failing rabbits. (ap26113.com)

Chemoreceptors2
There is certainly convincing proof that insight from arterial chemoreceptors right now, that through the carotid body especially, exerts a regulatory impact on sympathetic outflow under regular circumstances (Stickland et al. (ap26113.com)
These outcomes support the idea that improved basal activity through the carotid body chemoreceptors plays a part in the sympathetic activation in center failing. (ap26113.com)
Peripheral1
The autonomic nervous system ( ANS ) (or visceral nervous system ) is the part of the peripheral nervous system that acts as a control system, maintaining homeostasis in the body. (wikidoc.org)

We have demonstrated that, under relaxing normoxic circumstances actually, carotid Rabbit Polyclonal to BCAR3 body nerve release is elevated which inhibition from the carotid body decreases renal sympathetic nerve activity in center failing rabbits (Sunlight et al. (ap26113.com)
The nTS also receives input from a nearby chemosensory center, the area postrema , that detects toxins in the blood and the cerebrospinal fluid and is essential for chemically induced vomiting and conditional taste aversion (the memory that ensures that an animal which has been poisoned by a food never touches it again).

Mechanisms3
To further elucidate the amygdala-independent mechanisms leading to aversive emotional experiences, we retested two of these patients (B.G. and A.M.) to examine whether triggering palpitations and dyspnea via stimulation of non-chemosensory interoceptive channels would be sufficient to elicit panic anxiety.

8. The results indicate that, in rat carotid body type I cells, both nicotinic and muscarinic acetylcholine receptors increase [Ca2+]i, but achieve this via different mechanisms. (ox.ac.uk)
The presence of OMP in these cells indicates that the olfactory system may participate in shaping the chemosensory CB function.Conclusions: The findings support the notion that the transduction mechanisms of chemoreceptive systems contain a degree of homology, irrespective of the anatomical localization and the functional role these systems fulfill.

Increased degrees of reactive air varieties and angiotensin II having a concomitant reduced bioavailability of NO inside the carotid body appear to play a pivotal part in the introduction of improved carotid body chemosensory activity in pacing-induced center failing rabbits (Schultz, 2011).
