|---|---|
| Myocardium | Muscular layer of the heart |
| Sympathetic | nerves of the ANS that originate from the thoracolumar portion of the spinal cord; active when the body is under stress |
| Parasympathetic | active when the body is a rest or trying to restore body energy and function |
| Acetylcholine (ACH) | neurotransmitter of parasympathetic nerves; stimulates the cholinergic receptor; excitatory neurotransmitter in the basal ganglia |
| Norepinephrine (NE) | nerves that stimulate adrenergic receptors |
| CHF | chronic heart failure |
| Edema | swelling caused by fluid in body tissue |
| CAD | coronary artery disease |
| Arteriosclerosis | Hardening of the arteries |

| Cholesterol | fat normally synthesized by the liver; essential for the structure and function of cells |
| Anticoagulant | inhibiting the coagulation of the blood |
| Thrombocyte | cell in the blood; platelet, necessary for coagulation |
| Antichloinergic | drugs or effects that reduce the activity of the parasympathetic nervous system |
| Cholinergic | nerves that release acetycholine; drugs that stimulate the parasympathetic nervous system |
| Hyperlipidemia | high fat levels in the plasma |
| Exogenous | originating or produced outside the organism or body |
| Endogenous | occurring within the body; originating or produced within an organism, tissue, or cell |
| Afferent | transmits sensory information from peripheral organs to the brain and CNS |

| Parkinsonism | symptoms of Parkinson's Disease. tremors, balance. |
| Neurotransmitter | stimulates internal organs to produce characteristic changes associated with sympathetic and parasympathetic divisions |
| Stimulant | a substance that raises levels of physiological or nervous activity in the body |
| Depressant | drug reducing functional or nervous activity |
| Seizure disorder | abnormal discharge of brain neurons that cause alteration of behavior and /or motor activity |
| CNS | central nervous system |
