About Head's paradoxical reflex, which of the following fact is TRUE?
Head's paradoxical reflex: Inflation of lungs, under ceain conditions, enhances inspiratory activity. Since inflation induces fuher inflation of lungs, the reflex is considered paradoxical. The vagal fibers mediating Head's paradoxical reflex carry information originating in receptors present in lungs. This reflex has a role in initiation of respiration at bih.

It plays an impoant role in normal respiration
It is mediated by tracheobronchial-stretch receptors
It is stimulated by hyperinflation of lungs
It inhibits respiration
