Pulmonary Pharmacology [Part 1] | Bronchoconstriction & Bronchodilation Mechanisms

The video explains the balance between bronchodilation and bronchoconstriction, focusing on the physiological processes and pathways involved. It covers the sympathetic nervous system's role in bronchodilation through adrenergic pathways and norepinephrine release, and the parasympathetic system's role in bronchoconstriction via cholinergic pathways and acetylcholine. The video also discusses the enzymes and proteins involved, such as myosin light chain kinase, and sets the stage for future videos on drug effects.
