Csf chemoreceptors
WebChemoreceptors (KE. -mo. -re. -sep-terz) are specialized nerve cells that detect small changes in the concentration of specific chemicals or compounds. In general, chemoreceptors respond only to water-soluble and lipid-soluble substances that are dissolved in body fluids [interstitial fluid, blood plasma, and cerebrospinal fluid (CSF)]. WebApr 1, 2014 · We discuss evidence concerning potential mediators of these changes, including the following: 1) correction of alkalinity in cerebrospinal fluid; 2) increased sensitivity of carotid chemoreceptors; and 3) augmented translation of carotid chemoreceptor input (at the level of the central nervous system) into increased …

WebCarbon dioxide is the most influential and tightly controlled chemical regulator of ventilation. Carbon dioxide crosses the blood brain barrier and is converted to H + by the same reaction catalyzed by carbonic anhydrase. Elevated brain extracellular fluid (or Cerebral Spinal Fluid) H + concentrations are detected by chemoreceptors in the ...

Webchemoreceptors are the receptors that sense changes in levels of H+ ion concentration in the arterial blood and brain respectively (see table below) The medulla oblongata contains the respiratory control center and the lungs act as an effector. Blood pH levels are maintained in a normal range of 7.35-7.45. A drop in pH will bring
