lower airway ganglion

lower airway parasympathetic ganglion

A parasympathetic ganglion that is located within the airway walls of the lower respiratory tract. This ganglion is responsible for controlling the constriction of the airway by stimulating smooth muscle contraction in the lower respiratory tract to regulate airflow.

अक्सर पूछे जाने वाले प्रश्न

What is a lower airway ganglion?
A lower airway ganglion is a parasympathetic ganglion located within the walls of the lower respiratory tract — including the bronchi, bronchioles, and other airway structures. It contains postganglionic parasympathetic neurons that receive signals from preganglionic fibers of the vagus nerve and relay information to airway smooth muscle and glands.
Where is the lower airway ganglion located?
Lower airway ganglia are embedded within the walls of the lower airways, from the main bronchi down through the smaller airways. They are found within the connective tissue and smooth muscle layers of the bronchial tree and are distributed throughout the lungs along the branching airway network.
What is the function of the lower airway ganglion?
Lower airway ganglia are responsible for transmitting parasympathetic nerve signals that cause bronchoconstriction — the narrowing of airway lumen through smooth muscle contraction. They also stimulate mucus secretion from submucosal glands. These responses are part of normal airway regulation, particularly in response to inhaled irritants.
What conditions may affect the lower airway ganglion?
Alterations in the activity of lower airway ganglia may be associated with increased bronchoconstriction and airway hyperresponsiveness, which are features observed in bronchial asthma and chronic obstructive pulmonary disease. Modulation of parasympathetic ganglionic transmission is involved in the mechanism of some bronchodilator medications.
How is the lower airway ganglion examined?
Lower airway ganglia are examined histologically in lung or bronchial tissue samples. Immunohistochemical staining for neuronal markers such as S100, synaptophysin, and acetylcholine-related enzymes is used to identify and characterize ganglion cells within airway wall specimens.
