[Pulmonary vagal afferents in man].
Vagal afferentation from the lungs is mediated via various types of nerve fibers and is a prerequisite of numerous pulmonary reflexes. A review of studies on the morphology and functional examination of pulmonary vagal receptors is presented. Apart from the most frequently studied pulmonary stretch receptors also the role of irritant receptors and C-fibers is described. It is difficult to verify in man findings from animal experiments. Therefore, the studies testing the existence of pulmonary vagal reflexes in man are emphasised in the review. The importance of vagus nerves in cough, breathlessness, tachypnoea, in the control of the work of breathing and in the pattern of breathing is mentioned.
