1.

Sleep Latency

The time it takes to reach REM SLEEP. It is typically measured by POLYSOMNOGRAPHY or EEG as a part of various sleep pattern tests (e.g., multiple sleep latency test). [from MeSH]

MedGen UID:
1383175
Concept ID:
C4505222
Finding
2.

Norepinephrine

A naturally occurring catecholamine hormone that functions as a neurotransmitter in the sympathetic nervous system. Norepinephrine directly stimulates adrenergic receptors. Stimulation of alpha-adrenergic receptors causes vasoconstriction of the radial smooth muscle of the iris, arteries, arterioles, veins, urinary bladder, and the sphincter of the gastrointestinal tract. Stimulation of beta-1 adrenergic receptors causes an increase in myocardial contractility, heart rate, automaticity, and atrioventricular (AV) conduction while stimulation of beta-2 adrenergic receptors causes bronchiolar and vascular smooth muscle dilatation. [from NCI]

MedGen UID:
45125
Concept ID:
C0028351
Hormone; Organic Chemical; Pharmacologic Substance
3.

Amphetamine

Chemical racemic free base or equal parts of enantiomers levoamphetamine and dextroamphetamine in their pure amine or salt forms. [from SNOMEDCT_US]

MedGen UID:
266
Concept ID:
C0002658
Biologically Active Substance; Organic Chemical; Pharmacologic Substance
4.

Dopamine

A monoamine compound with positive inotropic activity. Dopamine is a naturally occurring catecholamine formed by decarboxylation of dehydroxyphenylalanine and a precursor of norepinephrine and epinephrine. Dopamine binds to alpha-1 and beta-1 adrenergic receptors. Mediated through myocardial beta-1 adrenergic receptors, dopamine increase heart rate and force, thereby increasing cardiac output. Alpha-1 adrenergic receptor stimulation on vascular smooth muscle, leads to vasoconstriction and results in an increase in systemic vascular resistance. Stimulation of dopaminergic receptors in renal vasculature, leads to renal blood vessel dilation, and an increase in glomerular filtration rate, renal blood flow, sodium excretion, and urine output. [from NCI]
