Question | Answer |
Peripheral Nervous System (PNS) divides into | Somatic and Visceral |

As people age the production of ACH | Decreases |
A decrease in the production of ACH may cause | Constipation |
Alzheimer's Disease might be attributed to a lack of | ACH |
Stress and Anxiety can activate the | Sympathetic Nervous System |
Prolonged activation of the Sympathetic Nervous System (stress/anxiety) can cause | Weight Gain, Increased Blood Pressure, and Hypertension |
Meth and Cocaine are considered | Sympathomimetics (resemble EPI) |
Effects of Meth | Appetite Suppressed, weight loss, teeth loss (due to enamel strip), temporary drug induced schitzophrenia |
What type of relationship does the Sympathetic Nervous System and the Parasympathetic Nervous System have with each other? | Inverse relationship (negative). As one goes up the other goes down. As one gown down the other will go up. Always seeking equilibrium (balance). |
Visceral is a Latin for | Internal |
What is a neurotransmitter? | Chemical Messenger. A substance that stimulates internal organs to produce characteristic changes associated with sympathetic and parasympathetic divisions. |
Role of Serotonin | Mood, Appetite, Libido, Sleep, and Arousal (wakefulness) |
Role of Dopamine | Limbic system (reward), voluntary decision making, Motor (skeletal) Muscle movement. Acts as a vasodilator. Inhibits NE. |
Role of Norepinephrine (NE) | Increases Blood Pressure, Increases Heart Rate, Increase Anxiety States, Increase Manic State, and affects mood |
What happens when NE levels are high? | Possible Mania, Cardiac Problems, and Schizophrenia |
Role of Acetylcholine (ACH) | sleep, arousal, pain perception, modulation and coordination of movement and memory retention |
What happens when ACH levels are high? | Possible Depression |
The parasympathetic division is more active during digestion and elimination of waste products and when the body is at | rest |
NE does not stimulate | Beta 2 receptor sites |
EPI stimulates | Beta 1, Beta 2, and Alpha receptor sites |
Adrenergic receptors accept | NE and EPI |
Adrenergic receptors are classified as | Beta-adrenergic or Alpha-adrenergic |
Alpha-adrenergic receptors are found mainly on | Smooth muscle membranes: small arteries, capillaries, and small vessels |
Alpha-adrenergic blocking drugs are used to clinically cause | Vasoconstriction of blood vessels |
In hypotensive states, drugs such as norepinephrine, and metaraminol, are given by IV injection to | Raise Blood Pressure |
Levophed | Norepinephrine |
Mimetics | do the same as the real thing (mimic) |
Lytics | slow down effects (inhibit) |
Blockers | act as antagonist (interferes with drugs or substance from producing a drug effect) |
