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.

bronchoconstriction

Narrowing of a bronchus, bronchostenosis

bron·cho·con·stric·tion

(brong'kō-kŏn-strik'shŭn)
Constriction of the bronchi.

bronchoconstriction

Contraction of the circular muscles in the walls of the bronchi, so narrowing the bore of the tubes and restricting air entry. See also BRONCHOSPASM.

bron·cho·con·stric·tion

(brong'kō-kŏn-strik'shŭn)
Constriction of the bronchi.

bronchoconstriction (brong´kō-kənstrik´shən),

n the reduction of the caliber of the bronchi.

bronchoconstriction

bronchostenosis.
