| 词条 | Juxtacapillary (J) receptors |
| 释义 |
The stimulation of the J-receptors causes a reflex increase in breathing rate, and is also thought to be involved in the sensation of dyspnea, the subjective sensation of difficulty breathing.[4][5] The reflex response that is produced is apnea followed by rapid breathing, bradycardia, and hypotension (pulmonary chemoreflex). The physiologic role of this reflex is uncertain, but it probably occurs in pathologic states such as pulmonary congestion or embolization.[3] These receptors were discovered by Dr. A.S. Paintal.[6] Because these receptors have been found in the walls of bronchi, the larynx, and the nose, they appear to be part of a widespread population of nociceptors found in most tissue. For this reason, they are now usually referred to as pulmonary C-fiber receptors.[7] References1. ^{{cite book|last=Sircar|first=Sabyasachi|title=Principles of Medical Physiology|isbn=1-58890-572-1|pages=350–51}} 2. ^{{cite book|last=Guyton|title=Textbook of Medical Physiology|year=2011|publisher=Saunders Elsevier|chapter=Regulation of Respiration|isbn=978-1-4160-4574-8}} 3. ^1 {{cite book|last=Ganong|title=Review of Medical Physiology, 25th ed. |year=2016|publisher=McGraw-Hill Education|chapter=Regulation of Respiration|page=662|isbn=978-0-07-184897-8}} 4. ^A.A.
