Hering-Breuer reflex

He·ring-Breu·er re·flex

(hēr'ing broy'er),
the effects of afferent impulses from the pulmonary vagi in the control of respiration; for example, inflation of the lungs arrests inspiration with expiration then ensuing, whereas deflation of the lungs brings on inspiration.

Hering-Breuer reflex

[her′ing broi′ər]
Etymology: Heinrich E. Hering, German physiologist, 1866-1948; Joseph Breuer, Austrian physician, 1842-1925
a neural mechanism that terminates inspiration and initiates expiration. The reflex is triggered by impulses that originate in stretch receptors of the bronchi and bronchioles in response to distension of the airway, increased intratracheal pressure, or pulmonary inflation. The impulses travel via afferent fibers of the vagus nerves to the medullary respiratory center. The Hering-Breuer reflex is well developed at birth and is hyperactive in conditions of restrictive ventilatory insufficiency.

Hering-Breuer reflex

Neurology A reflex in which lung distension stimulates stretch receptors, which act to inhibit further distension

Her·ing-Breu·er re·flex

(her'ing broy'er rē'fleks)
The effects of afferent impulses from the pulmonary vagi in the control of respiration, e.g., inflation of the lungs arrests inspiration, with expiration then ensuing, whereas deflation of the lungs brings on inspiration.

Hering-Breuer reflex

A feedback system for controlling breathing. The stimulation of stretch receptors in the bronchi and lungs, occasioned by breathing in, eventually causes the DIAPHRAGM and the muscles between the ribs (intercostal muscles) to cease contracting. (Heinrich Ewald Hering, 1866–1918, German physiologist; and Josef Breuer, 1843–1925, Austrian physician)

Hering-Breuer reflex

a protective mechanism that prevents excessive inflation of the lungs in diving mammals.
