ANS BasicInfo
Cards that review the basics of the autonomic nervous system.
| Question | Answer |
|---|---|
| How does the stimulation of alpha-1 receptors affect the BLOOD VESSELS? | Causes vasoconstriction, inc. BP, inc. contractility of the heart. |
| How does the stimulation of alpha-1 receptors affect the EYE? | Causes pupil dilation. |
| How does the stimulation of alpha-1 receptors affect the BLADDER and PROSTATE? | Causes contraction. |
| How does the stimulation of beta-1 receptors affect the HEART? | Causes increased force of contraction and increased heart rate. |
| How does the stimulation of beta-1 receptors affect the KIDNEYS? | Causes increased renin secretion, which leads to increased angiotensin. This increases BP. |
| How does the stimulation of beta-2 receptors affect the SMOOTH MUSCLE of the GI tract? | Causes decreased GI tone and motility. |
| How does the stimulation of beta-2 receptors affect the LUNGS? | Causes bronchodilation. |
| How does the stimulation of beta-2 receptors affect the UTERUS? | Causes relaxation of the uterus. |
| How does the stimulation of beta-2 receptors affect the LIVER? | Causes activation of glycogenolysis, which increases the levels of blood glucose. |
| Name 3 neurotransmitters of the SYMPATHETIC nervous system. | Norepinephrine* (main neurotransmitter in sym. NS), epinephrine, dopamine. |
| Name the neurotransmitter found in the PARASYMPATHETIC nervous system. | Acetylcholine (ACh) |
| What is the purpose of the body's SYMPATHETIC response? | "Fight or Flight." HR, BP, blood sugar will all inc. Broncho- and pupil dilation. |
| What is the purpose of the body's PARASYMPATHETIC response? | To "rest and digest," i.e. slow the body down in times of non-stress. Opposite of sympathetic response. |
| What are the CARDIOVASCULAR uses for adrenergic agonists? | Cardiac arrest, hypotension, shock, heart failure |
| What are the RESPIRATORY uses for adrenergic agonists? | Treatment of asthma & COPD. |
| What are the NASAL and OPTHALMIC uses for adrenergic agonists? | Treatment of nasal congestion; glaucoma. |
| What are other uses for the adrenergic agonists? | Treatment of premature labor and hypoglycemia. |
| Name the uses of the alpha-blockers. Examples: "-zosin" | Treatment of: Hypertension, BPH, Raynaud's, post-partum bleeding, migraines. |
| What are the side/adverse effects of alpha-blockers? | CV: ORTHOSTATIC HYPOTENSION, tachycardia, palpitations, edema, dysrhythmias. CNS: Dizziness, headache, etc. GI: N/V/D, abdominal cramps GU: Inc. urine freq., incontinence, impotence. |
| Beta-blockers typically have what suffix...? | "-olol" |
| What are the uses of the selective beta-blockers, such as metoprolol (Lopressor) and atenolol (Tenormin)? | To treat hypertension, angina, acute MI. |
| What are the uses of the NON-selective beta-blockers, such as propanolol HCl (Inderal)? | To treat hypertension, angina, dysrhythmias, post-MI. |
