'Inflation of the lungs will induce fuher distension'; this is referred to as:: (A) Hering-Breuer inflation reflex, (B) Hering-Breuer deflation reflex, (C) J-reflex, (D) Head's paradoxical reflex
Answer is D. Head's paradoxical reflex is an example of positive feedback; distension --> fuher distension --> fuhermore distension. This occurs at bih, when the lungs are in a collapsed state and they are beginning to function thereafter. J-reflex:- Stimulation of J-receptors (pulmonary edema/congestion) --> apnea followed by rapid shallow breathing, bradycardia, hypotension.
