 Context examples 

A benign lung neoplasm arising from the alveolar/bronchiolar epithelium.

(Alveolar Adenoma, NCI Thesaurus/CDISC)

Diffuse accumulation of groups of neuroendocrine cells confined to bronchiolar epithelium in the absence of airway inflammation or diffuse interstitial fibrosis.

(Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia of the Mouse Pulmonary System, NCI Thesaurus/MMHCC)

In addition, isoproterenol acts on beta-2 adrenergic receptors in bronchiolar and vascular smooth muscle, thereby causing smooth muscle relaxation.

(Isoproterenol, NCI Thesaurus)

Stimulation of beta-1 adrenergic receptors causes an increase in myocardial contractility, heart rate, automaticity, and atrioventricular (AV) conduction while stimulation of beta-2 adrenergic receptors causes bronchiolar and vascular smooth muscle dilatation.

(l-Norepinephrine, NCI Thesaurus)

Groups of uniform small cells with scant cytoplasm and round to oval nuclei with dense speckled chromatin form clusters thickening bronchiolar wall and/or protruding into the lumen.

(Neuroendocrine Hyperplasia of the Mouse Pulmonary System, NCI Thesaurus/MMHCC)

Stimulation of the beta-2 adrenergic receptors causes bronchiolar and vascular smooth muscle dilatation.

(Levarterenol Bitartrate, NCI Thesaurus)

A malignant lung neoplasm originating from the alveolar/bronchiolar epithelium.

(Bronchioloalveolar Carcinoma, NCI Thesaurus/CDISC)

Dioxifedrine selectively binds to and activates beta-2 adrenergic receptors in bronchiolar smooth muscle, thereby causing stimulation of adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3',5'-adenosine monophosphate (cAMP).

(Dioxifedrine, NCI Thesaurus)

Clorprenaline selectively binds to and activates beta-2 adrenergic receptors in bronchiolar smooth muscle, thereby causing stimulation of adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3',5'-adenosine monophosphate (cAMP).

(Clorprenaline Hydrochloride, NCI Thesaurus)

In bronchiolar subvariant, also called bronchiolization of alveoli, alveolar walls are lined by cuboidal to columnar cells with features of bronchiloar differentiation such as formation of cilia, Clara cell resemblance and presence of mucous granules.

(Alveoli Epithelial Hyperplasia of the Mouse Pulmonary System, NCI Thesaurus/MMHCC)
