The Hering-Breuer inflation reflex is a protective mechanism that limits inspiration. Which pathway and receptor type are responsible for this reflex?
Show answer and explanation
Correct answer: Stretch receptors in airway smooth muscle signalling via the vagus nerve
The Hering-Breuer reflex is initiated by pulmonary stretch receptors located in the smooth muscle of the bronchi and bronchioles. When the lungs overinflate, these receptors send inhibitory signals to the medullary respiratory centers via the vagus nerve to terminate inspiration.
