aortic body造句

• Inputs to this neuron come from the peripheral chemoreceptors, carotid body, aortic body, and central chemoreceptors.
• Peripheral chemoreceptors ( carotid and aortic bodies ) and central chemoreceptors ( medullary neurons ) primarily function to regulate respiratory activity.
• Some sources equate the " aortic bodies " and " paraaortic bodies ", while other sources explicitly distinguish between the two.
• Chemoreceptors present in the carotid body or adjacent to the aorta in an aortic body respond to the blood's oxygen, carbon dioxide levels.
• Clusters of glomus cells, of which the carotid bodies and aortic bodies are the most important, are called non-chromaffin or parasympathetic paraganglia.
• 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.
• When a distinction is made, the " aortic bodies " are chemoreceptors which regulate circulation, while the " paraaortic bodies " are the chromaffin cells which manufacture catecholamines.
• When a distinction is made, the " aortic bodies " are chemoreceptors which regulate Circulatory system, while the " paraaortic bodies " are the chromaffin cells which manufacture catecholamines.
• 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.
• Similar changes in sensitivity have been found in women administered levels of hormones that mimic the stage of the pregnancy in which these effects being to appear, suggesting that carotid and aortic body sensitivity is modulated by neuroendocrine processes.
• Since it is not stained by chromic salts, it is not truly a part of Chromafin system, the system which includes cells stained by chromic salts, consisting of renal medulla, para ganglia, and para aortic bodies.
• Collecting information on carotid and aortic body activity in live, exercising humans is fraught with difficulty and often only indicates indirect evidence, so it is hard to draw expansive conclusions until more evidence has been amassed, and hopefully with more advanced techniques.
• In healthy individuals the presence of elevated carbon dioxide levels in the blood lowers its pH . Chemoreceptors found in carotid bodies and aortic bodies detect a decrease in blood pH and send this information to the RCs which then signal the respiratory muscles to breathe.
• Both carotid and aortic bodies are composed type I and type II cells and are believed to receptors is still an active area of research, and not all studies agree, but there is growing support for a transduction mechanism dependent upon mitochondrial consumption of oxygen affecting the AMPK enzyme.
• A "'glomus cell "'( type I ) is a peripheral chemoreceptor, mainly located in the pCO 2 ), the carotid bodies and the aortic bodies signal the medulla oblongata ( specifically the dorsal inspiratory center in the medulla oblongata ) to increase the volume and rate of breathing.
• The term "'para-aortic body "'is also sometimes used to describe it, as it usually arises near the abdominal aorta, but this term can be the source of confusion, because the term " corpora paraaortica " is also used to describe the aortic body, which arises near the thoracic aorta.
• The term "'para-aortic body "'is also sometimes used to describe it, as it usually arises near the abdominal aorta, but this term can be the source of confusion, because the term " corpora paraaortica " is also used to describe the aortic body, which arises near the thoracic aorta.
