Limitation of inspiration by vagal lung inflation

Limitation of inspiration by vagal lung inflation signals is called the

A. Autonomic reflex 

B. Bainbridge reflex
C. Hering - Breur reflex 
D. Dynamic stretch reflex

Ans.  (c) Hering - Breur reflex

·         The shortening of inspiration produced by vagal afferent activity is mediated by slowly adapting receptors

·         So are the Hering - Breur reflexes

·         The Hering - Breur inflation reflex is an increase in the duration of expiration produced steady lung inflation, and the Hering – Breur deflation reflex is a decrease in the duration of expiration produced by marked deflation of the lung

·         Because the rapidly adapting receptors are stimulated by chemicals such as histamine, they have been called irritant receptors
