bronchoconstriction

 [brong″ko-kon-strik´shun]
narrowing of a bronchus as a result of smooth muscle contraction, as in asthma.

bron·cho·con·stric·tion

(brong'kō-kon-strik'shŭn),
Reduction in the caliber of a bronchus or bronchi, usually referring to a dynamic process as in asthma and emphysema, rather than a fixed constriction (the latter is a bronchial stenosis). Compare: bronchospasm.

bronchoconstriction

/bron·cho·con·stric·tion/ (brong″ko-kun-strik´shun) narrowing of air passages of the lungs from smooth muscle contraction, as in asthma.

bronchoconstriction

Etymology: Gk, bronchos, windpipe; L, constringere, to draw tight
a narrowing of the lumen of the bronchi, restricting airflow to and from the lungs.

bronchoconstriction

The narrowing of a bronchus due to the contraction of the surrounding smooth muscle, which may be caused by either histaminic-H1/2 or muscarinic (M1/2/3) receptors.
