Psychology Terms - Alcohol
Ethyl alcohol, a colorless volatile liquid and central nervous system depressant substance created by the fermentation of sugar, serving as the psychoactive component in intoxicating beverages. Its pharmacological mechanism, although not entirely elucidated, is partially attributed to the enhancement of the inhibitory neurotransmitter *GABA, likely via the activation of the GABA receptor complex. While the absorption and bioavailability of alcohol are influenced by body weight, sex, recent food intake, and various other factors, approximately one unit of alcohol (equivalent to one half pint of beer, one glass of wine, or one measure of spirits) consumed by an average individual weighing 150 lb (68 kg) typically results in aA blood alcohol concentration (BAC) of approximately 20 mg/dl results in significant impairment in performance on intricate hand-eye coordination tasks. Consuming two units in rapid succession, with alcohol typically metabolized at a rate of one unit per hour, elevates the BAC to 40 mg/dl, further impairing visual acuity. Three units correspond to a BAC of 60 mg/dl, resulting in a loss of coordination. Seven units yield a BAC of 140 mg/dl, accompanied by confusion, slurred speech, and ataxia. Twelve units result in a BAC of 240 mg/dl, leading to coma, while 14 units culminate in a BAC of 280 mg/dl, resulting in death. Upon alcohol consumption, inhibitory processes diminish initially, leading to an amplification of spinal reflexes and the emergence of behaviors (such as talkativeness, exuberance, and aggression) typically moderated by social inhibition—this explains the erroneous belief that it acts as a central nervous system stimulant. Also referred to as ethanol. Chemical formula C2H5OH. Alcoholic adj. 1. Pertaining to alcohol. A person with a dependency on alcohol. alcohol dependence Alcohol dependence
