| Questão | Responda |
| 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) |
