Central and Peripheral Nervous system.
| Question | Answer |
|---|---|
| Andrenergic | Drug that stimulates receptors for epinephrine or epinephrine. |
| Parasympathetic system | Controls SLUD |
| Sympathetic | fight or flight system |
| What are the 2 major control systems in the body | 1. Nervous 2. Endocrine |
| Function of sensory(afferent) neurons | detect change in light, heat, pressure, pain in CNS |
| Somatic(motor)neurons | responsible for voluntary muscle movements |
| ANS | Involuntary, unconscious control mechanism of body |
| What is the Neurotransmitter at the Parasympathetic end | Acetycholine (strong bronchoconstrictor) |
| Neurotransmitter at the sympathetic end | norepinephrine/epinephrine |
| What terminates acetylcholine & norepinephrine | cholinesterase & catechol-0-methyltransferase( COMT) and MAO - monoamine oxidase respectively. |
| Effects of parasympathetic system on the cardiopulmonary | 1. Decreased heart rate 2. Low BP 3. Bronchoconstriction 4. Mucus secretion |
| Muscarinic | Receptors at parasympathetic end. M3 is on airway smooth muscle mediating bronchoconstriction. |
| Atropine | Typical parasympatholytic or anticholinergic. Blocks parasympathetic site |
| Sympathetic effects on the cardiopulmonary system | 1. Increased heart rate 2. Increase BP 3. Bronchodilation 4. Increased secretion from mucus glands in the airway. |
| Sympathetic end receptors | Alpha - vasoconstriction B1 - Inc heart rate B2 - Smooth muscle relaxation |
| drugs refer to page 95 | pg 95 |
| What is the neurotransmitter at the sympathetic end | Epinephrine |
| Sympatholytics(Adrenergic blocking agents) | - inhibits the SNS - |
