| Front | Pulmonary innervation |
|---|---|
| Back | All innervation arises from the cardiopulmonary plexus (at the tracheal bifurcation) and enters the roots of the lungs. Parasympathetic - from vagus nerve - bronchoconstriction - vasodilation (pulmonary arteries) - secretomotor (glands of bronchial tree) Sympathetic - from thoracic and cervical sympathetic trunk - bronchodilation - vasoconstriction - inhibitory to glands of bronchial tree Viscerosensory via parasympathetic pathways - Bronchial cough reflex - Pressoreceptors in pulmonary arteries - Chemoreceptors in pulmonary veins - Cyclical control of inhalation/exhalation |
