Definition
1. Regulate heart
2. Regulate secretory glands (salivary, gastric, sweat, bronchial)
3. Regulate smooth muscles (bronchi, blood vessels, urogenital, GI) |

If patient is having an asthma attack and difficulty breathing, which drung would you to patient?
a. Sympathetic agonist
b. Parasympathetic agonist |
|
Definition
| Answer A. because sympathetic dilates brochi, which helps to improve oxygenation. |

| Functions of Sympathetic Nervous System |
|
Definition
1. Regulation of cardiovascular system
2. Regulate of body temperature
3. Implementing flight or fight reaction
- Increase HR & BP
- Shunting blood from viscera to skeletal muscle
- Dilating bronchi to improve oxygenation
- Dilating pupils
- Mobilizing stored energy and provide glucose

|
Definition
| Answer C. Blood vessels are innervated by sympathetic nervous system only |

Term
|
Definition
| Baroreceptors (BRs) are receptors that sense the blood pressure (BP), monitor changes in BP |
