Adaptation of pulmonary stretch receptor in different mammalian species

摘要: Abstract A consequence of the adaptation pulmonary stretch receptors is that their pattern discharged depends on both lung volume and its rate change. For dependent, flow related information to modify breathing by a feedback process, appreciable receptor must take place during single respiratory cycle. Moreover, for have same significance in all animals, time course would vary among species, being more rapid small with high frequencies. We recorded fiber action potentials from 84 six species mammals, ranging hamster dog. The response maintained transpulmonary pressures was similar different as following sudden inflations 5 10 cm H 2 O. These findings show behavior animals widely differing frequencies, regulation mustvary interspecifically.
