Controlling Airflow

Pregunta	Respuesta
Bronchoconstriction- (Vagal Nerve)	Causes a release of AcH, which activates phospholipase CBeta
Bronchoconstriction- Phospholipase CBeta	Produces IP3 and activates Myosin Light chain Kinase (MLCK) which causes bronchoconstriction
Bronchodilation- SNS	SNS increases cAMP levels, deactivating Phospholipase CBeta, inhibiting MLCK and inc. inc Ca2+ binding in the cell
Asthma (Definition)	Reversible airflow obstruction
Characteristics of Asthma	Fluctuating bronchoconstriction, inc mucus secretion and airway inflammation
Symptoms	Wheezing, coughing, chest tightness
Intermittent Symptoms	Tend to be worse at night
Triggers	Tend to be produced by triggers- pet fur, dust, pollen
Diagnosis- Peak Expiratory Flow	Greatest airflow that can be sustained on forced expiration (varies in asthma patients, red at night)
Diagnosis- Forced Expiratory Volume	Amount of air forced out in 1s
Diagnosis- Forced Vital Capacity	Total volume of air that can be exhaled forcibly
